Yes, but how that country-specific tagging is implemented matters.

Rest of world uses A=B to denote objects of type P.  Country X decides that
A=B
denotes objects of type Q.  Definitely not good.

Rest of world uses A=B to denote P.  Country X decides that A:xx=B denotes
Q.  But that
may also apply to country Y so either mappers in Y use A:xx=B or a synonym
A:yy=B to
denote Q.  Still not good.

We decide that A=B denotes P globally and that A=C denotes Q globally.  Or
we have
A=B + subtag=P or subtag=Q.  Works well.

Yes, there are likely to be many country-specific variants that aren't
quite identical.
But still better handled with more tag values or subtag values than by
sticking country
codes everywhere.  Semantically either way means the same thing but one is
preferable syntactically and for sanity.

Yes, local government has extra complications that mean it's not as simple
as new values.
But probably soluble by means other than sticking country codes all over
the place.  Even
admin_level=4;5;6 would be better than that.
