real world explanation: in the late 90s small and sleek is the trend.
in universe explanation: as a weapon of war the smaller it is the better, smaller target, smaller heat signature, lighter, more agile, easier to concealed.
sf on the other hand is the exaggeration of everything. It is blink bcuz ppl like shinny stuff especially kids. Its disproportionately large wing span compared to its body is cuz overly complex retarded backpack is seeds signature. As a weapon of war, sf is pretty much useless.
hence ur question should be the other way around. The bigger elephant in the room is sf.

not to mention literally useless when there is gravity around

but as a design, i can appreciate it, but as a weapon of war, it's really ridiculous
Eh, the in-universe explanation is a moot point. It's a (science?) fiction, and the anime clearly expresses them as capable of maneuvering and fighting effectively given whatever their looks or complexities are, in their respective series

I can accept your point, however, if only some MS (particularly the Gundams) to have smaller builds compared to the antagonists' MS, but that's not the case, seeing UC MS are indeed shorter.
