No need to worry, I shall never do something like that. As mentioned a
couple of days ago, my library is written so that all additions to musl
will take place in the form of architecture-specific sub-folders, as is
the case today with mips, x86_64, etc.

Not really an assumption, just an attempt to better understand things.
The answers I received were enlightening and very useful, and thus saved
me a lot of time. I also do not recall trying to object to the current
musl implementation, hence the use of question marks and the subjunctive
mood in my original post:)
>> I don't understand why this new approach thinks it won't encounter

You know, sometimes dreams come true. Maybe mine will be one of them.
