well the handling problems would be more complicated for simple reasons.
Uv light makes up a very small part of the visible light spectrum.
So you can transfer and handle resins more easily and with less degradation (solidification) than a visible light resin.

You also need to make sure that the print area is opaque to light as well.
I don't suppose they're particularly difficult issues, you just need to take more care when using the resin that no extraneous light enters the printer.
