Are you referring to more fonts being imported or more fonts being imported at once?

It certainly allows multiple fonts being imported, but regarding their parallel import some tricks and workarounds could be found here. Most of them probably aren't worth implementing on your wiki, though, it will probably not be too much of a performance hit if you import more than one font in your wiki's CSS.
