FWIW, I see no compelling reason for this change, even after I've read
the explanations. This keyword is a cue to the compiler, so it in
general conveys non-trivial information. If today's compilers mostly
ignore that, it doesn't mean this will always be the state of affairs.
However, by removing this, we lose those cues forever.
I guess I won't be convinced without seeing at least some data about
the disadvantages, and not just a few extreme examples with some
particular versions of some specific compilers.
But this isn't my call, so perhaps you don't need to convince me.
