Not relevant for me. I don't support multiple monitors at the moment, and I have no plans to add such support anytime soon.

Just a clarification here. There is no problem with supporting multiple monitors in the graphics API, as every graphic operation goes via a handle, which might refer to an in-memory bitmap, a physical screen or a printer. The needed modifications would be to add the ability to create handles that refers to multiple monitors associated with UEFI.

This is a valid argument. However, while you are doing the long mode port anyway, it costs almost no time extra to make it UEFI-compatible. You do not have to write the actual loader yet.
