I don't know about never, there's plenty of more lolicon
works than this that are wholesome
(Some of Itou Hachi's work).
I don't really like the idea of loli
as a tag since it seems like it would get overused for things that just have lolis present; eg. 3gatsu no lion, yuru yuru, etc; instead of indicating that they're involved in the romance as the one with the crush or something similar; this, the structural formula of first love.
