It is perfectly reasonable to deprecate the variable. However it is
better to show the user how to fix the problem in their code than just
break previously working code (for some definition of working).
How about renaming all occurences of `bidi-display-reordering' to
`debug--bidi-display-reordering' or similar, and then add something like:
(make-obsolete-variable 'bidi-display-reordering
"not used. To disable reordering, use `(setq bidi-paragraph-direction
'left-to-right)' instead." "27.1")
That would less hostile to users than immediate removal.
