I mean, it's not like 5e is free of such things, the list is just shorter because there's less in 5e, purely in terms of fewer books (often shorter ones too, mechanically, since each book is meant to appeal to any possible buyer: player, DM, worldbuilder, etc.) The endless complaints about Lucky, PAM/SS/GWM, etc., show that there's still some of that going on. Every Sorcerer (especially Dragon Sorc, double especially Fire ones) should take Elemental Adept to deal with enemy resistances. "Just pick something at 3rd" is kind of a misnomer when it comes to 5e, because while it does apply for some things, for others it's much more complicated...especially spellcasters.
That said, you aren't wrong that there's a certain amount of...shall we say, not very interesting "baked in" feat expectations. Not truly expected, per se, but implicitly so. I think some of that is fine. 4e may have included too much, 3e definitely included too much. Something not so much halfway between 4e and 5e as...like two thirds of 4e, say? Enough mechanical richness to be engaging, but keeping in mind the need to avoid past excesses.
