There is no way for strmode(3) to append '+' if the file has ACL,

Yep, that '+' is why libarchive has a custom strmode()
that accepts more information than just the mode.
A related issue: It would be really nice to be
able to find out whether a file had extended ACLs
or extended attributes based on the information
returned from stat(2).
I know about the idea of adding a bit to the inode flags, but I never
thought about exposing it to the userland in mode_t. Can we actually
do this without risking confusing some applications that expect only
the standard mode bits to be set?
Unfortunately, mode_t is very full and extending
it would probably cause chaos.
I was thinking of a bit in the fflags field.
That wouldn't help strmode(), of course,
but would make it easy for strmode() users
(such as ls) to add a '+' if they wanted to.
