I disagree, though like with everything it needs to be easily scanned & laid out well. I've had a few where people have put them in categories — Expert: A, B, C; Intermediate: …; Learning: … — which personally I've liked.
Without the list — if you don't have at least familiarity with, e.g. Bash/Git, it's a big minus & I'd prefer to know that before the interview stage.
Sometimes people go for concise & hit sparse, which is definitely worse :) Even on a two-page CV, you could fit in a version of this if you remove a "Personal Statement" or "References available on request" (I'd hope this is a truism!)
It seems like there's a balance somewhere. Enough to communicate versatility and proficiency, but not enough to loose the signal in the noise.
I like the leveling idea (expert/intermediate/learning).
I'm all about taking out things that feel superfluous like the personal statement (isn't that the cover letter?) and references upon request (if they ask for references of course I'll give them, who isn't going to give references upon request?).
