I've been noticing this a bit lately too, though I haven't been editing excessively. I find I spend the first chapter or so of a new novel noticing little things I never had before - an unusual word used multiple times, for example (unless insouciant is common and I've been living in a hole in the ground), or something that I would have punctuated or phrased differently. If the story is sound, however, I'll get sucked in, regardless of the number of adjectives.
