One of the problems with going to DIP 1000 by default is what to do about `ref return scope` ambiguity. Walter had finally come up with a fix that was half-implemented. Some of the PRs had been merged, but others were stalled. Those stalled PRs are blocking progress on DIP 1000, and he wants to get those moving.
Status update: the `ref return scope` ambiguity is fixed now ([PR 13693](https://github.com/dlang/dmd/pull/13693)), as well as the invalid [pure->scope inferrence](https://github.com/dlang/dmd/pull/12989) and [inout->return inference](https://github.com/dlang/dmd/pull/12689). Currently, most remaining open issues are related to nested functions. Atila resumed work on making dip1000 the default [by printing deprecation messages for scope errors](https://github.com/dlang/dmd/pull/12578).
