The answer to your second question is yes.

Regarding the first:  If the user uses
  LIBTOOLFLAGS="--tag=CXX"

in a package with
  foo_SOURCES = foo.c bar.cc baz.f

he'll have a problem.  Surely enough, setting the tag has its uses in
LIBTOOLFLAGS sometimes, and also per-object *_LIBTOOLFLAGS can be
useful here as well (you just described how to employ per-object flags).

Yep.  I did not mean to say setting --tag in *LIBTOOLFLAGS was a bad
idea in general.
