It's about as easy to ignore one as it is to ignore the other.
Not really.
Rewriting mechanics requires playtesting for balance, errata for when inevitable problems crop up, teaching people the new rules, having to peruse every release for ways to adapt them to the new mechanics, etc.
Rewriting lore is as simple as "Drow are actually jungle elves who are nocturnal" and watching as precisely no mechanics conflicts come up and not a single bit of playtesting is needed. If you get a "that sounds cool, tell me more" from the players, you've done very well.
See? Not remotely the same thing and massively easier to ignore lore.
