Thanks.  But note that setting bidi-inhibit-bpa non-nil will help
significantly only for files that are likely to have a lot of bracket
characters, especially if they are nested.  So maybe do that in
so-long.el only for modes where this is likely to happen, if not by
actually counting such characters.  E.g., I wouldn't recommend doing
that in Text mode, since there it might cause incorrect display
without any real benefits.

Characters that I call "bracket" for this purpose are listed in
admin/unidata/BidiBrackets.txt (a file we import from the UCD).
Significantly, the "<>" pair is not there, so files with lots of those
particular brackets will not be affected by this issue.
