Thanks for this amazing simplification - so much workaround code being deleted! 😻 I found only one occurrence of damage (impressive for such a large PR), and identified a few opportunities for cleanups while looking at the surrounding context of the changes:

This PR mechanically changes preprocessing conditions involving
__cpp_lib_conceptsto say_HAS_CXX20, and then removes some redundant conditions.Most of the replacement is done in the first commit (5e05034), which is completely mechanical (see commit message).
Commit 7687eec removes occurrences of
#if _HAS_CXX20within#if _HAS_CXX20blocks.Commit ba1dd83 removes occurrences of
#if _HAS_CXX20within#if _HAS_CXX23blocks.Commit 730bca0 removes occurrences of
#if _HAS_CXX20within tests that use*_20_matrix.Commit e303104 removes occurrences of
#if _HAS_CXX20within tests that use*_latest_matrix.The other commits are tiny cleanups.
Fixes #395.
Blocked on #4296.
