Hmm, note that C++ is also used for LLVM/JIT, and by requiring this
additional feature set we are also imposing new requirements for those

new requirement at the last moment.
I understand the hesitation, but in practice we already impose those
requirements anyway for non-MSVC compilers because test_cplusplusext
doesn't compile without it. So any compiler that would cause problems
with the new featureset would have already complained about that
before.
But how about this: We add the feature test that you propose and enable
the extension based on that. See attached patch. This reduces to
essentially a three-line patch, much simpler than all previous proposals.
If you're still worried, then this sounds like a fine middle-ground
for now. I think we should reconsider adding the automatic /std:c++20
flag for the PG20 dev cycle though.
Ok, I have committed the shown patch.
