Usually someone submits a change, and later gets notified that the 
change was dropped from master-next due to a musl issue.

That's not fun.

And all these compile errors with musl due to header order are a real WTF,
every other library (not limited to C libraries) is now doing headers 
properly so that any order works. No fun in supporting a broken design.

I was not asking for "modern".

If init scripts are not default and CI tested with musl,
then init scripts will soon become a broken part of OE.

I already tried patching musl in OE.
The change got reverted.

There are people who think that OE-specific patches to musl are not 
acceptable, and that it is better to force everyone in OE to patch 
individual packages all the time instead of adding a not upstreamable
patch to musl.
