The underlying motivation for adding those aliases seems to be missing from the description.

Personally, I do not see the point of adding aliases to save two characters (you only save the "20" part of "clc++2021"), while adding potential confusion ("is the language called //C++ for OpenCL 2021// or //C++ for OpenCL 21//, or maybe it has something to do with //OpenCL 2.1//?").  Also they are being added as deprecated aliases, suggesting they might be removed at some point in the future again?

I'd much rather see one canonical way of specifying the language version, instead of adding multiple aliases to do the same thing.  But perhaps there is a good reason that I am not aware of?
