This was implemented in gcc 11 with this commit:
https://gcc.gnu.org/git/?p=gcc.git;a=commit;f=libcpp/init.c;h=445430e16bd08ade34637d2346ded40dd49de508
Closing.
Cheers,

Is this released on any gcc 10 point release version (as per debian stable
support)?

No. C++20 support in GCC 10 is missing a number of features, so it would be
misleading/incorrect to define it to 202002L.
https://gcc.gnu.org/projects/cxx-status.html#cxx20
You can just test for > 201703L if you want to know if partial C++20 support is
present. Or use the feature test macros for individual features.

--- Comment #10 from Marco Trevisan <mail at 3v1n0 dot net> ---
I see the point, but then I also think that gcc-10 should not support
`--std=c++20` option but rather only the `--std=c++2a` one.

No, because that just makes it more awkward to write makefiles and build
scripts. We used to do that, and it had no real benefit. If you want to use
c++2a, you can use that. Other people just want to use c++20 across multiple
releases, some of which have full C++20 support and some don't.
To check the level of conformance you should check the macros defined by the
compiler when compiling, not rely on which command-line options happen to be
supported.
