That's actually not true for java at google.  However, after warning
bankruptcy was declared, a small set were made into errors and the
rest suppressed.  So that supports the idea of categorizing warnings
into serious and advisory, and using -Werror only for serious ones.
Of course, choosing which ones are which is likely to be a wrangle.

In my personal code I do the same, that is try to make it warning free
but only enable warnings that I consider worthwhile.  It would also be
really nice to have pragmas to suppress warnings locally (e.g. ErrorT
deprecation warnings from transformers-4, which seem to be impossible
to fix without abandoning 7.8).
