Did you complain about 2E kits this much?
First, admittedly, I have very little experience with 2e kits; I got started with D&D toward the end of the AD&D 2E run.
However, I never saw kits as a "design crutch," per se. Kits are an extra option to layer on top of your character. They may have improved some classes, or added an option that players felt was necessary, but they weren't "gain bonus feats," or "gain more options for this ability you already have." Perhaps not well-designed, but they were also not lazy design.
An extra theme is simply a number of bonus feats. An extra background is a number of bonus skills. Adding a feature is good design, in my opinion. Just doubling the number of feats for a fighter (even if the second choice is from a restricted list) is lazy.
I do, however, understand the difficult in creating a balanced, useful, and enjoyable feature for the fighter that improves your ability to "hit stuff." Just because it's challenging doesn't mean designers should take the easy route.
