--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Since concepts have no runtime overhead I don't see any advantage to being able
to disable them.
Arguably, since the option is documented as enabling the Concepts TS, we could
claim that -fno-concepts disables the TS, but leaves C++20 concepts enabled :-)
A warning saying it has no effect would make sense though.
