They are not portable to broken bash. But the argument in these threads
is that bash's implementation of function exports should be changed so
that _fixed_ bash will once again be POSIX compliant and let this
bog-standard assignment work regardless of contents. If Chet accepts
Florian's patch [1] to change function exports to use BASH_FUNC_foo()=
instead of foo= (which is what Red Hat is already using in their fixes
pushed today), then this POSIX compliance bug in broken bash will be
avoided.

IS this added only in memory? I.e. no changes to source code?
What prevents BASH_FUNC_foo = '(){ :; ...';
Why is there a need for a long prefix on top of switching
the ()/= order?
