They're not yet relying on that behavior when using %language.

Automake's Yacc rules depend on Yacc's file name conventions not Bison's.  
Thus, if you use Bison in Automake in this way, you specify -y.  So, -y 
should probably override %language for the output file names.  Thanks for 
mentioning this.

Akim and I once discussed how it would be nice if Automake supported Bison 
directly.  In that case, Automake could document what file names it 
expects.  It could choose the ".tab"-less convention I'm proposing so that 
users would be encouraged to use %language.
