You're effectively proposing that the library be renamed to avoid the
SONAME conflict, with symlinks left behind for backwards compatibility
(run-time and compile-time).

I agree with that plan.  The krb5-config, .pc files, and docs should be
updated accordingly. 

It helps to have clarity: SONAME conflict -> library name change.
