No, it's a compilation error:

(Maybe I'm just holding it wrong and I badly packaged apex)

Tehcnically yes, but the team is currently

• under staffed
• lacking compute, both for CI and development/testing

So we're doing our best to keep the lights on and things somehow up to date. All the extra, as much as we'd love to do (and I truly do) is currently out of scope.

(Having said that, backporting this one to 26.05 shouldn't be too bad. Don't hesitate to open a PR, I'll try to do it today otherwise)

Opened the backport PR :) : https://github.com/NixOS/nixpkgs/pull/527055

Testing is ongoing
