Getting rid of yes on issues that have been resolved but not yet published or are in a similar high-confidence scenario removes useful information and I really would like us not to do that.

For unresolved issues currently marked as unimplemented, it is probably a good thing to just say unresolved. That we do not implement something for which the resolution is unclear is not useful information to our users.

For issues implemented but unresolved (ie yes/clang xx). these are implementing a particular proposed resolution (either because 1/ we are confident the resolution has been or is going to be resolved as proposed or because we think the resolution make sense and is important to implement)  and that offers useful information. We should keep that information.
We could clarify further with a footnote along the line of "This issue has not been resolved by the C++ committee and its resolution is subject to change".
