The set-theoretic platinum standard



It is commonly asserted that ZFC is the set-theoretic gold standard.
You can always assume these axioms, without specifying that this is
what you are doing.

However, in some cases, mathematicians have been quietly taking
Tarksi-Grothendieck set theory as the standard instead. This is
ZFC+inaccessible cardinals. In algebraic geometry, and therefore in
proofs that rely on algebraic geometry, use is sometimes made of such
proceedures as using the axiom of replacement within a universe within
a universe. The Mizar project, which was discussed on a JST thread,
bases its rock-solid, computer-verified proofs on Tarski-Grothendieck
set theory.

Does anyone want to vote in favor of the proposition that ZFC is OK,
but Tarski-Grothendieck isn't? Is Tarksi-Grothendieck the unofficial
platinum standard of mathematics?
