I had an impression that good versioning system helps evolution but not 
prevents it.
Like in C/C++ world it allows to make compilers better e.g. to fix old bugs.

Each C/C++ compiler has its own vendor/version identifier. No one known 
compiler is pretending to be another one.
Conditional compilation feature allows library/application vendors to 
support set of compilers (read: UAs) and not only one.

I suspect that FireFox can be compiled by different compilers. And these 
compilers may differ pretty significantly.
I think that without conditional compilation feature that is built-in in 
C/C++ such projects as Gecko were even possible.

I think that Web will benefit from conditional CSS includes. It will 
make possible new features to be implemented safely.
