>>395715Are they about a girl experiencing adult perks and responsibilities in a controlled setting, which will lead her to grow up mature and well-adjusted? Symphogear sort of had that, but only in the first season. Most of its cast are already adults by this point.
Quite a few of those shows wouldn't be considered magical girls in Japan (or would be considered a mix of genres). In particular, Kill la Kill is a Go Nagai homage more than anything, just like Tengen Toppa Gurren Lagann was a Ken Ishikawa homage.
