I'd rather have to make hard choices about space in the PHB (which literally could just be a bit bigger than it is), maybe lose a couple pages of spells, some other stuff, and have more interesting entries on the peoples of the multiverse.
OTOH, I don't think we will ever* have to worry about it, because 6e isn't coming.
*It's more likely now than ever before, but still very unlikely that wotc will ever make a new edition of dnd again without first having a prolonged loss of sales for 5e, and instead they will work on things like the crossovers, different styles of DnD as side projects, etc.
