Hi Serhii,
With Enums supported in PHP 8.1, I think this pattern of using
constant names with identical values will see fewer use cases.
I also don't think that a proposal to add new common keywords like
`uppercase` / `snakecase`, or adding any magic to constant names
(because PHP 7 supported case-insensitive constants) will be received
well either.

Thanks,
Ayesh.
