Are there any plans to allow multiple classes as a theme-source?

I'm seeing this being asked a lot of times e.g. Help_talk:PortableInfoboxes?diff=1563158&oldid=1563157.

The general use-case seems to be people wanting to change the color of the infobox based on the page settings. Although this is currently possible with either a separate theme for each page or an @import in each of the "theme-sources". It is possible that the pros do not outweigh the cons.

Lots of imports may be a bad idea (ref ) anyway.
