For painting oneself to a corner, are there much options?
Yes there are, but you may not like them in total.
Stick with CS6 as long as you can. You lose out on any new functionality coming but maybe it's not useful or necessary.
Move to another product. Kiss all your layers good-by. And any other proprietary image processing developed by Adobe you've used on your images.
Move to CC and be happy with some things, unhappy with others (it ain't a perfect world, Adobe isn't a prefect company that pleases everyone).
Recognize we're talking about a tool here. I have no idea if you make any money with the tool or the tool is used in a hobby that sucks money out of your pocket. Either way, the upgrade to CC is either a sound proposition or it isn't.
The idea:let's buy into CC, love some of the new features, then decide screw it, I'm leaving the party is fine. But to expect you can move back to an older version that doesn't support new functionality and be upset that you can't is as silly as deciding you'll go back to Photoshop 2.5 and complain it can't open any of your layered files. This back and forth version jumping scenario is as silly today as it was in the mid 90's when all of us using PS back then moved from 2.5 to 3.0+ and the product
now supported layers. The only difference is there's a new subscription model and people are thinking of silly toughts like, how can I use new features and go back to an older build and use features that didn't exist. That's not going to work. This is nothing new.
Draw a line in the sand NOW. Move forward to CC or don't. This '
I want my cake and eat it' idea of using CC for awhile, then deciding not to will work if you do diligence and only use the features of CS6 in CC, assuming you wanted to move back to that version (not CS5, or CS3). That seems like a dumb move.
