This is somewhat similar to #432562. The difference, as I see it, is
capital letters + compatibility with Ubuntu versus underscores +
compatibility with BSDs. I don't see that any of the breakage concerns
originally raised in #432562 apply to this suggestion.

I am also in favor of reducing unnecessary incompatibilities that can
cause confusion. People of #432562, do you have any comments?

regards
Afif
