Yes, but no. Looking at the examples you use just doesn't make sense.
Take your killer elf fighter. Since he didn't max his strength, instead going for Dexterity, he is limited to 5th level. That means that your dual-wielder never even gets to have multiple attack routines.
And although his "to hit" won't be that bad, his lack of strength means very little damage. But wait- he's a fighter/MU! Again, we have a terrible Fighter (max 5) and a mediocre MU (max 9) since you made Dexterity your top stat.
And all that so that you could ... get a secondary attack with a hand axe or dagger. It's just not the smart play. Most of these "builds" just don't make any sense in the context of pre-UA 1e, and only limited sense even after UA.
EDIT- the main point is that unlike more recent editions, COUGH 5e COUGH FINESSE, you couldn't get damage bonuses with Dex. Ever. If you wanted the massive to hit ... AND DAMAGE bonuses in AD&D, you needed strength. And because so many other classes were actually dex-dependent (Thief, Assassin, Monk, Illusionist) it was likely that high-dex characters were not fighter, or, at most, were MC fighters that would never get to the level that would let them have multiple attack routines.
