Yes that is correct. GCC simply checks if a symbol is part of a comdat
group and if it is, emits .linkonce for it's section. GAS then sees
the directive and moves the symbol corresponding to the section name
to be the first symbol so it becomes the key. See:

Sounds good to me! Don't think I'd be qualified or have the know how
to make this change but the testsuite above should hopefully be of
use.
