But they are larger, and unnecessarily so. And some classes will need to skim the larger list for specific schools, which is an additional and cumbersome level of complication (exponentially more so for the new to that class player, who has to keep in their head what particular schools they are looking for).
Overall, currently the OneD&D plan is to make a newer players both digest more spells (possibly keeping school in mind) as well as the feat system to make informed choices at character creation. That's objectively worse design for newer players, and collectively the choices seem to indicate a direction of less concern for new players than went into 5e design. Even if the spell list change is "no big deal" on this front, it seems indicative of a larger trend towards catering to veterans at the expense of novices for the new edition.
You may not care all that much about new player accessibility, but, as someone who spends several weeks every summer helping large numbers of children roll up their first characters at a summer camp, it is a top priority for me. As a company trying to keep their game the gateway game for the hobby it should be a top priority for WotC as well.
