I want a convenient instrument to suppress unwanted diagnostics. Even if I change clang-tidy to ignore note locations, it would still be impractical to use '-header-filter' to //exclude// diagnostics from certain headers. Header filter was designed to //include// headers, not to //exclude// them. Trying to exclude "these m directories and that n files" is close to impossible using a single regular expression. Plus, even if I manage to do this, I'll be ignoring all diagnostics and not only the faulty ones.

Suppress-check-filter is specifically designed to //exclude// headers and doesn't require abusing regular expressions to do this. Plus, it allows a user to specify what diagnostics he doesn't want, instead of ignoring everything.
