My motivation came from my first attempts to write the documentation for LATM. It means that the prospective user coming to the top-level synopsis is plunged immediately into the SLIF's least perspicuous syntax, and advanced issues. I could just tell the user to treat the two lines you suggest as a magical incantation for now, but why not make the magic look unforbiding?

But is this (new token) really an improvement over getting the user to specify their defaults explicitly?

After all, you could just put:
    lexeme default = forgiving => 1 # Recommended
    :default ::= action => ::array        #  Ditto
in the synopses.
