Similarly this is why, in some places, people report having "that old XP machine running <software> in the closet" because <software> is really important to them and they have no path forward (it doesn't support > XP, it's actually too vital - though that seems like an odd reason not to update, etc.).

You could replace these things with something newer but the concerns by various parties can outweigh the willingness to fight and you probably don't want to be on the receiving end of "I told you so".
