Proposed resolution (approved by CWG 2025-11-06):
Change in 11.7.3 [class.virtual] paragraph 18 as follows:
A class with a consteval virtual functionshall not overridethat overrides a virtual function that is not consteval shall have consteval-only type (6.9.1 [basic.types.general]). A consteval virtual function shall not be overridden by a virtual function that is not consteval.

The current prohibition against overriding a non-consteval virtual function by a consteval virtual function (inside a consteval-only type) is too restrictive and prevents implementation of std::meta::exception.
