I like it. Among other things, it might allow one serializer to fall back to another. E.g. if YAML doesn't find a freezer defined for it, it could theoretically fall back to DDS.

The only other way that I think might make sense is for a package to have the hash, e.g.

our %FREEZE_THAW_FOR;
%FREEZE_THAW_FOR{ "Data::Dump::Streamer" } = [ 'foo', '->bar' ];
%FREEZE_THAW_FOR{ "Data::Dumper" } = [ 'foo', 'bar' ];
%FREEZE_THAW_FOR{ "YAML" } = [ 'foo', 'bar' ];

It all amounts to the same thing really -- mapping between packages and serializers in some package variable space. I think I moderately prefer your approach, though a part of me is leery of the globals either way. Seems like there ought to be a better way -- maybe a third party module that packages can register with and serializers can query, but then you wind up in dependency hell.

I think the KISS and YAGNI principles would suggest doing it your way.
