I agree that APFS is implemented for SSD drives.

I'm asking why is everyone discussing whether to use APFS or HFS+ format for Pro Tools Audio sessions, without addressing Avid's own requirements indicating "Media on APFS drive : No" ?

The following is copied from Avid page on Hard Drive formatting for Pro Tools Sessions :
