Because for a user 'other-frame' may be TRT for most bookmarks but not
for a few specific ones.

No.  It's the way the command specifies the behavior: If it does so by
binding a global variable, the result may be equivocal when the user
has customized 'display-buffer-alist'.  If it does so by setting the
ACTION argument, the result is unequivocal.
