I was thinking to have standard SYM_CODE default to a section then a
variant for anything that cares (like how we have SYM_FUNC_PI and
friends for the PI code for EFI).

Right, I meant that I was expecting to see things that need to be in a
specific section other than .code.text called out separately here if
we're enumerating them.  Though if the annotations are done separately
then this patch wouldn't need to do that calling out at all, it'd be
covered as part of fiddling around with the annotations.
