WarpOS binary format is tricky.
Just bad design.
Do you remember the "runelf" program ? The same should be possible with Wos.
Adding WOS support is not that simple really.
My personal thought is that I prefer spending time on working on something usefull than on things from the past !
But OS4 got PUP emulation, right? If so, better ditch WOS apps now and go for PUP versions.
