Whatever the size of the constituency for printing profile targets, the functionality to do it properly and easily should be there, and if it confuses some people, so be it - all they have to do is a bit of reading to sort it out for themselves.
There are several good reasons that Adobe has dropped No Color Management from the print dlog...first off, as Eric indicated, it doesn't ALWAYS work correctly with ALL OS and driver configs...to get it to "mostly work" was an enormous effort that could be broken with an OS update (as Apple has shown repeatedly) and subject to failure with faulty print drivers (as Epson has recently proven). But people don't seem to be willing to accept that the faults are not with Adobe so Adobe shoulders the blame. Adobe is not going to to a dot release for Photoshop every time something breaks in the hack to make NCM work. So, Adobe removed the option...
One CAN still print targets without using the NCM path...it's the work around that Eric came up with to overcome Epson's 79/9900 driver problem with CS4. Tag the untagged file with Adobe RGB, in Print, set Photoshop to manage color, set Adobe RGB as the output profile forcing a null transform then in the print driver set it to no color management (or whatever the drivers things is no color adjustment).
I'n not sure that is any more difficult and confusing than using the old No Color Management approach...it's a couple of extra steps...but if somebody can follow directions, it shouldn't be all that more difficult...
Reread Eric's last line...
"Adobe believes this is the best long-term approach to serving the needs of users who build their own printer profiles, for a number of technical, practical, and political reasons."
The technical and practical reasons should be obvious...but the toughest problem to deal with is the "political" problems. You can hack around the technical issues but when Adobe is put in the middle between the OS's and print drivers, it's a no win situation. Adobe got tired of shouldering the blame and Photoshop is an expensive application to have to use to print out targets...that's why it'll actually be easier (and ultimately better) to have a free, cross platform application designed SPECIFICALLY to properly print color targets...it'll be easy to rev the tine amount of code (compared to Photoshop) to deal with OS dependancies and to address driver issues. Ultimately it is the proper solution. It'll just tak a bit of time to get the printing app done and posted. In the meantime, use the work around for CS5, or use CS4 or CS3 or even use Apple's Preview on the Mac...ain't no big dealio, ya know?
