1056	a supported extension to support (un)reifying deferred warnings	fare		"ASDF 2.26.x introduces support for saving deferred warnings and re-playing them in a different session.

It currently does it by peeking and poking at the internals of CCL (and SBCL). Could you export a supported variant of that functionality in CCL 1.9 and later?

See the code in asdf/lisp-build.lisp. The entry points are
reify-deferred-warnings
unreify-deferred-warnings
reset-deferred-warnings
