The fate of Hebrew texts with Hyphen-Minus instead of Maqaf

For the sake of the argument, let's assume that Hebrew Punctuation Maqaf
is now part of the official keyboard layout; that it is implemented well
(both in fonts and keymap) in all major operating systems; and that users
of Hebrew accept the new addition and start to use it from then on. What
will be the fate of all Hebrew texts that used Hyphen-Minus instead? are
they doomed forever to render wrongly under applications that use the
Unicode BiDi algorithm? by wrong, I strictly refer to the way the
original authors intended them to render.
