Eh nook, then make Custom background default and later put in few suggestion. with advice that some if not all suggestions can be tweaked.
Honestly best class description was in 3/3.5e
every class came with one or two feat suggestion and what skills to take at 1st level.
Custom background should be a DM allowance.It's in the DMG because there is that 10% of players who will customize a background outside the power range of the rest of the party.
People are really only complaining because they are only a few 2024 backgrounds.
If there were no art and triple the backgrounds, 75% of people complaining about Custom background not being in the PHB would be gone
