Suggestion: can we make an ASDF-specific subclass of STYLE-WARNING so
that programmers have the option of catching it and handling it?

Here's why I ask:  at our company, we routinely have Jenkins jobs where
we fail on even style-warnings (otherwise people got sloppy and left
them around, leading to real bugs not being caught).  Now we simply have
a zero-tolerance policy.

If one has to use a library that uses deprecated ASDF functions while
it's being fixed, it would be nice to be able to muffle just such
warnings, instead of having no option but to pull out the big club and
muffle all style warnings.
