Originally Susan Richards' powers were turning invisible and creating a force shield around herself. This wasn't for doing cool things, it was for staying safely out of the way while the boys did the fighting. By the mid 70s when I was buying comic books her purely defensive powers were upgraded to being able to produce a shower of spherical force bubbles, which on the offensive force scale was about one step up the awesomeness scale from telekinetically throwing couch pillows.
I don't think the reason for this change was to throw a sop to feminists, or because fans were demanding strong female characters. In either case she'd have got a more impressive upgrade. I think it was simply upgraded storytelling. A character that can basically hide and shield herself is not as versatile as a character than can do useful things. So this kind of incremental upgrading naturally gave her more of a swiss-army knife skillset.
As for modern superheroines having multiple, I have not much to add, other than an observation. This multiple super-power thing kind of mirrors what we expect women to be like today. We expect them to be able to multitask, to juggle several very different roles on our teams. Versatility has become a cultural expectation for women, so it might not be coincidental that female superheroes get more of toolkit rather than one very big hammer.
