Shall we remove abseil checks?
Shall we remove libc++-specific checks?
Shall we remove webkit checks?
Shall we remove backwards-compatibility checks?

Nothing is ever useful for everyone. Much like `-Weverything`,
enabling all checks comes with an explcit caveat that
one needs to disable the checks that are not applicable for the codebase.

+1 to having this check.
