I hope they will reconsider removing this one. This will cause lot of software to lose silently the verbose error reporting and nobody will notice until it is too late (unless it is caught by the test suite, which mean that test suite of older version will fail which is quite painful when bisecting).

I agree, also for YYPARSE_PARAM and YYLEX_PARAM. Parsers are often write-and-forget, which means for programs such as Bison (unfortunately) there is no long-enough deprecation period.

Maybe they should make bison to output a deprecation warning for two release
before the removal.

The only thing that _might_ work is printing an error and forcing people to add a --deprecated command-line option. And even then I'm not sure...
