Description Denys Dmytriyenko 2026-04-20 21:42:40 UTC 
This is a "feature request" and not a bug with the current design. It is intended for the TSC to keep track and potentially address in the future, as it will be a breaking architectural change.

This has come up in the past:

https://bugzilla.yoctoproject.org/show_bug.cgi?id=2964
https://bugzilla.yoctoproject.org/show_bug.cgi?id=12688

One of the justifications for such potentially major architectural re-design is easier YP Compat compliance, as discussed in the second bug entry above.

This is something we want to do. Richard is on it.
