... The question asked is completely different than most people reply (which is usually out of subject) and has to do whether some customers would prefer to use faster, cheaper, simpler & more reliable lenses if higher sync FP shutter was offered by the makers... 

Might as well ask if photographers would rather use a diffraction-limited 400mm f/2.8 that weighs 1/3 as much and has twice the DOF as the current CaNikon lenses and doesn't damage any credit cards to purchase.  What's wrong with CaNikon?  Why aren't they making this lens?  It's obviously a conspiracy to make us buy the shorter and/or slower lenses that have been sitting in their inventory for decades.

I believe it is common sense that the existence of leaf shutter lenses has nothing to do with FP shutters existing along side them and with the sync speed of FP shutters... All todays MF cameras but the Hasselblad H system provide FP shutter and are able to use LS lenses (Pentax 645 too) if the maker decides to offer them.

Obviously there are people that would choose to use higher sync LS lenses and others that would prefer faster & cheaper lenses instead... The question asked is completely different than most people reply (which is usually out of subject) and has to do whether some customers would prefer to use faster, cheaper, simpler & more reliable lenses if higher sync FP shutter was offered by the makers... 

Note that the UWAs offered by ALL makers that have bodies with FP shutter in production are only offered without LS shutter included and this is because there is no use for a high sync UWA lens...

the answer to your question is yes. however given the history and current situation, that yes is not expressed by enough customer to be worth it for MF manufacturers .... satisfied ?

I honestly think leaf shutters are now just about as fast as they will ever get. Making the shutter twice as fast, for example, means twice the acceleration on shutter blades (possibly the problem is stopping them) and four times the energy needed to accomplish that. Demand for faster lenses = larger shutters makes the problem even worse. There is simply no demand enough to spend R&D money on something as esoteric, using fullerene blades and cryogenic magnets to move them. Forget it.

The question of this thread seems to have come down to why one company, Hasselblad (the only maker of a system without an FP shutter AFAIK) does not invest in designing and deploying a focal plane shutter system at least twice as fast as any other 645 system offers, and considerably faster than even the glorious somewhat smaller format Leica S system offers, to be deployed in addition to the continued offering of leaf shutters in most lenses, in order to potentially allow a few future wide angle lens designs to cost less by omitting the leaf shutter.

At a guess, it is because the cost of developing that imagined new FP shutter technology would be too high compared to the lens cost savings and the new sales attracted to Hasselblad by the ability to offer those few less expensive lenses.  But does anyone here have any evidence on the costings on this? I doubt it.

And, by the time they got done, global shutters might be on the horizon for MF, and who would care?

Can this thread end?

There isn't anything being discussed that hasn't been stated a few times over, and the OP's 'design ask' has been answered with there isn't a market justification to do it.

How? ...did you see anyone presenting a marketing research that claims so?

It's exactly the  reasoning that is the fundamental behind logic.... Thus, the luck of reasoning reveals the trolls....  ;)

Unlikely:  all you trolls have got to stop picking on Theo.
