Given the flavor text around 3e magic, at least for traditional Vancian casters, where you spend some time in the morning "preparing" your spells, and all you do in combat is complete them, it makes perfect sense that it takes no longer to complete a 9th-level spell than a cantrip. And it's less bookkeeping.
As for weapon speeds, I've never seen a system that makes sense; there's at least as much logic behind 'longer weapon=faster' as there is in the 2e-style 'smaller weapon=faster'. So they're in the ashbin of gaming history as far as I'm concerned.
So it's a NO; I wouldn't ever play with them. There are some obscure corner-case exceptions (i.e. playing with long-standing friends or celebrities who insist on using them), but in general, I wouldn't touch them again.
