Profile compatibility confusion

It seems like the p1s profiles are not compatible with any of the newer printers and I’m not sure why.

I suspect it’s still a print-by-object issue, but it’s really inconsistent.

In this model for example Infinite Train Starter Set - Free 3D Print Model - MakerWorld most of the profiles don’t appear for H2, P2, X2 printers. Some of the profiles that use print-by-object DO appear in the list for those printers, so I’m not sure what the issue is.
Also, when I converted the main profile for X2D and uploaded it, it was still only available for X2D.
I also tried reuploading one of the missing profile and checking all the boxes for the h2 p2 x2 printers but it made no difference.

Seems like if I were to upload a profile for each printer, they’d get reported and removed. Given how much BL stresses testing and verifying models, it would also feel weird to upload a version for every printer without being able to test.

Incidentally the bambu panda has a similar issue.

How are others solving this?
