I think there's zero possibility of you not getting free Feat at L1 in DND2024.
Whether that Feat is determined by your background (either specifically or giving you a list), or chosen from a small list, or freely chosen, remains to be seen (I suspect both of the first two are more likely).
At this point, with 50m+ players, and only at most maybe 10m of them even potentially "burned" by Feats in 3E/4E/PF (and most people actually didn't hate Feats in those), I don't think Feats being optional or not is a "dealbreaker" for any significant proportion of the audience. So they can easily flip it so in the DMG you can just have the Background Feats and all other Feats are ASIs or whatever. Again very different to 2014 where nearly 100% of players were ex-3E/4E/PF.
Whether we also get on at L4 I think may well depend on feedback to this, but I think it's quite likely.
