What is simpler?
1) Fix a security hole by back porting a security fix
2) Re evaluate a completely new release
This is not a problem. And it doesn't take much to do #1... sure you have to find the right person to do it but it is far from impossible and expensive.... so no I am completely oblivious to corporations that just want to use something for free and then come a complain and whine that something isn't supported anymore... now if they had payed money for it then that's a completely different thing... doesn't RHEL6 support FF3.6 in any case? So there are options for these corporations that are utterly cheapass lazy and incompetent... however having said that... these enterprises will not survive for long so they should in no shape way or form dictate how a browser should be. If Microsoft and IE are fine with that thats their own big big problem. Stale stagnancy as with IE6 and nothing but problems and issues with that kind of an approach. Ok gotta stop before I blow a fuse.
