EWG discussed §2.4 of this paper in Kona on Thursday morning in response to cplusplus/nbballot#764 and cplusplus/nbballot#654, and took the following polls:
US 131-195 [meta.reflection.annotation] Support annotations on function parameters - we want to pursue a change for C++26

consensus.
US 42-078 9.13.12p1 [dcl.attr.annotation] Allow annotations of function parameters - we want to pursue a change for C++26
no objection to unanimous consent.
Forward §2.4 of P3795R0 - Miscellaneous Reflection Cleanup to CWG for inclusion in C++26 in response to US 131-195 and US 42-078
Note @jensmaurer : EWG discussed ONE section of this (2.4) and forwarded it for C++26 in response to a pair of NB comments. LEWG is likely to still want to discuss the other parts, but they are only vaguely related

CWG 2025-11-07 in Kona: Reviewed P3795R0; needs updates.
Question for EWG regarding explicit instantiations:
CWG felt this was inconsistent and asks EWG to review that inconsistency for rationale and/or rectify it.
