I agree, especially if a @setfilename different from the file name
is used on purpose to have a different output name than the base name.

I just tested a mismatch between filename and @setfilename with automake.
The file name is toto.texi and @setfilename my_output.info.  make info
works.  make html fails with:

make: *** No rule to make target 'toto.html', needed by 'html-am'.  Stop.

make my_output.html works.

I do not think that this needs to be fixed in case at Texinfo we
consider that @setfilename different from the file name is bad and that
@setfilename more generally should be deprecated.  My recommendation
would be to leave unsaid for now whether automake supports or not a
different file name than @setfilename for non generated texinfo manuals
in case it is later considered relevant, probably based on the advice
from the Texinfo crowd.
