I know, but at some point it was said only the C++ development version is fair game, which would mean C++26. Hence the proposal to discuss this. I was already considering to put it on the agenda after a private conversation with Victor.

The last time I had a patch to improve the transitive includes by `#ifdef-ing` it got a lukewarm response. So nice to hear the response now is better.
