I think this can be rewritten
(defun visual-file-name-abbrev--display-p (buffer pos path abbrev)
(run-hook-with-args-until-failure
'visual-file-name-abbrev-display-predicates
buffer pos filename abbrev))
which adds the ability to combine buffer-local and global parts.
I'd rename the var to use "-functions" as a suffix, to follow the usual
naming conventions.
BTW, why not pass the overlay as argument instead?

I understand you want the overlay to "auto-reveal" the text when point
enters it, but visual-file-name-abbrev--display-p seems "too dynamic" in
the sense that it recomputes a lot of things that could be computed
right here when building the overlay
(e.g. visual-file-name-abbrev--abbrev-shorter-p will always recompute
the same string-widths since the args it receives are always the same).
