I'll try.
I'm hesitant to ask MOS devs for much due to how much I've been (or seen other people be) chastised in the past. They're a great bunch that do awesome stuff, but I feel pretty intimidated about raising the ire of...well, let's say some of them.
I have good news, you don't have to walk into the lion's den. If you already did, then I hope you have survived.
Since the issue has been brought up again, and I had some idle time, I went ahead and fixed the problem myself. Being the bungler I am, I tried to mimic the interface of the MorphOS version of rtgmaster.library, which is compatible with WarpOS programs. This was a bad idea, because it has a mixed interface having both 68k and WOS functions, where Warp3D has two separate libs for this purpose (Warp3d.library and Warp3D_ppc.library). To keep the long story short, I now have Wipeout 2097 running with Wazp3D on MorphOS. I've sent my changes to Alain, the rest is up to him.
