There should not be any reason to have the ilmbase package as separate one, because this package has been incorporated into the openexr package itself (in version 3).
As per libHalf, this functionality has been moved into a new package imath, that was introduced by upstream with release of openexr 3 and is available in Fedora now.
Unfortunately, building OpenColorIO 2.0 failed to properly detect libHalf despite the inclusion of imath.
Extract below:

Now that the OpenEXR/Imath disaster is nearly over I'm going to turn my attention to OpenColorIO. Not many packages need it so this might be easier. I have already created an opencolorio1 compat package for those upstream that haven't ported to v2 yer.
Thanks,
