If I'm the DM, having to check the spell lists of my players' characters to see if they can even use the scroll I'm about to give them is a very unwelcome complication.
Whereas a simple "Does this party include a divine and an arcane caster? Yes, okay so all scrolls are fine!" was perfectly okay before.
