Mirco is this something that you could have a look?
The plugin supports up to version 12 of the XCF format. We are now at 20 or 21 in GIMP 2.99 and they will continue to add features until the official release. Looking at it now doesn't make much sense. I just tried to remove the rejection based on the version number and the image loads although the result is different than in GIMP 2.99 (which is a good sign).
