Thank you for the great work!

What was the reason given for not wanting to integrate this work with glibc?

Do you have a reference to the public discussion?

My personal inclination is to attempt to include this functionality in
glibc, but I don't have that much experience with the functions in
Annex K.

Perhaps others will comment.

Cheers,
Carlos.
