Yes, this Flymake backend is specific to this particular program because
1. the output pattern is probably more or less unique, 2. it needs a
dynamically computed argument and 3. Flymake allows several backends to
in parallel, so if a new linter comes into being, it's up to the user to
decide whether to run one or the other or both.
