Now, this is what bothers me about these kinds of discussions. And I’m not picking on you, Jack, because I’m indicting my younger self who said the same and much worse.
Don’t you think the people who came up with those rules, the people who gave feedback while playing them, and the people who edited them all thought that they were perfectly sensible?
Well...
Gygax himself said there are rules in 1e he included as "favors" to other players that he himself never used. (Psionics is one example) In addition, there are elements of 1e (and earlier) D&D that wasn't thoroughly playtested, just kinda created, eyeballed, played once, and sent to the printer. (IIRC, the unarmed system was never really run through its paces and added as an afterthought).
I once asked Gary (in the Enworld thread) basically what was he thinking about cavaliers raising physical stats. His reply, in essence, was "it is what it is". Not the most assuring explanation I've heard.

There are things in 1e that needed fixing for no other reason than to make the game smoother and more uniform (removing monks with they're odd ability score uses or fixing initiative). Second edition went a little too far in some cases (removing half-orcs left a strong-man void) so I think 2e was necessary at its time. I do think though that Cook needed another co-author to aid with his rather dry prose and I think the whole project needed a bit more oversight in its later supplements (Complete Handbooks, I'm looking at you). Cie la vie.
