   One notable difference to prior behavior is that "print x = 0"

It's fine, thanks.

Does this mean the feature will only work with GCC-compiled programs?
If so, perhaps we should say that more explicitly.

It will work with any program that uses exceptions where the exception
unwinder defines a particular debugging hook.

Right now this hook only appears in libgcc.

It would probably work right now with other compilers on systems using
a new-enough libgcc.  E.g., it might work for other compilers on Fedora.

Then I guess your wording is okay as it is.  Thanks.
