Guys,
I urge you not to move production machines to Sierra.
Wait it out, until a sufficient database on the issues builds up so they can be Googled, and give devs time to catch up with their fixes.
Most of my consultant friends are now really unhappy about new Apple software due to stuff breaking. My own Octave virtual machine server for Mac is broken so hard I don't (yet) know how to fix it, I think I will need to budget a week's time at least, and I cannot imagine what "real" developers can be going through as they struggle to keep their apps updated. A lot of stuff will fall through the cracks for a few months as devs struggle to remedy the damage, and in particular any workflow that involves AppleScript.
There was a time when devs tried to get apps working on a new system for release. This now seems to be an unrealistic target as everything depends on everything else, some of it open source from independent teams outside Apple, some like printer drivers commercial, so updating becomes an iterative process, you fix what you can, wait until others do the same, rinse and repeat. And let us not forget that each developer needs to bring his own dev machine back into a productive state, or rather set up a new installation and get it to work. As a result it takes about a year for a new system environment to settle down to productive stability.
Again, I urge you not to update any machine you rely on for income.

I'm not attacking, and not sure what issues those that are having problems are, but most of us use Lr, Ps, C1, and maybe a few other programs, as well as some color management software. I profiled two displays yesterday with i1Profiler, my friend and I have been running Sierra since it's release on two laptops and one 5k iMac and using this software extensively. Zero issues.
Certainly there are users out there which are involved in far different software than a typical photographer, and it behooves them to verify Sierra didn't break those. For photographers that might mean Affinity, some add ons or other packages Like Helicon Focus (which works).
So while your advice to be cautious is certainly wise, there seems to be enough anecdotal evidence that Apple didn't really change anything that would affect the typical photographers workflow and related software is working fine. On the other hand, other than some nice moves to help Apple devices interact more seamlessly and the addition of a functional voice command system for the computer, there isn't a lot of compelling reason to upgrade, so waiting means there won't be much to miss. (of course there are several under the hood enhancements, and
improved security is one, which might be a reason to consider it ... )
Upgrading is always a little bit of a risk, and I'm sure there are those who will install and find issues, but most of those will be related to something in their particular setup, not an overall problem, and waiting most likely won't change that. As for me, I didn't do a clean install, and plan on not doing a clean install on my Mac Pro as well. Both of those machines were clean installs with Yosemite.
One change I did notice which affected my friend, with Sierra the Desktop and Documents folder can be set to be stored on iCloud. Perhaps a nice feature if you use more than one Mac for some, but personally if I need something shared between two machines I use Dropbox, and really don't need those folders shared or stored on iCloud. Somehow when he installed, that feature was turned on, in my case it wasn't. Apparently he answered one question differently than I did during the installation.
