If you never played at those levels I can understand your position but we played those levels and it was quite fun. So yes, the "balance" was a poor one but it was an attempt nonetheless. Remember that RPG were in their infancy and a lot was yet to be fully understood.Not really you are just claiming something else balances a focused area of imbalance. That rarely works as you cannot control the frequency of the assumed other area. For instance 1e considered it balance that a caster got nearly nothing to contribute for several levels (unless they won the spell lottery then the game of DM vs caster began early) and were awarded later by over shadowing others except and individual game table often never hit all the levels and instead only felt imbalance.
So yes, one imbalance can be balanced by something else. It is also a matter of how many house rules you have and IF you took their repercussions onto account when implanting them. So far, 5ed is the closest we have for a balanced game where every classes feel unique and can contribute equally to the game. No other edition can claim that. Even if I much prefer 1ed, I can admit the 5ed is better designed than my favourite one.
In order, 1ed, 5ed and 4ed. 2ed was not going far enough and 3.xed went overboard with casters.
