Technically speaking, it still could. It'd just have to implement it itself via strings. But yeah, it probably doesn't do that (I can't speak about the implementation, I'm entirely uninvolved).

Though I've never actually encountered any errors because of that as my usecases are always pretty basic. Things like magic select, transparency, layers etc all work good enough that I haven't used anything besides this since I found out it ... sometime between 2015 and 2019.
