Yes, such a mechanism would be nice.  The Automake way wouldn't be to
allow 'foo_DEPENDENCIES +=' without prior initialization though (that
would defeat typo detection, and probably complicate the internal logic
wrt. conditionals), but adding of another variable to the default list
of foo_DEPENDENCIES.  I guess.  Suggestions for naming such a variable?

Thanks,
