But this is only for pasteboard support between the emulated and host systems, right? Do we really need 100% compatibility for that? As long as a PICT image on the emulated pasteboard gets translated to a TIFF or PNG or something on the host pasteboard and vice-versa 99% of the time, any rare corner cases should be only a minor inconvenience.
