I'm going to remove this since we are about to unify iccifort and iccifortcuda (so I have no toolchain to test this on, and we don't plan on having one).

I tested this locally:

alanc@~$ eb --module-naming-scheme=HierarchicalMNS intel-compilers-2021.1.2.eb -x | grep MODULEPATH
    prepend_path("MODULEPATH", "/home/alanc/.local/easybuild/modules/all/Compiler/intel-compilers/2021.1.2")
alanc@~$ eb --include-module-naming-schemes=hierarchical_mns.py --module-naming-scheme=HierarchicalMNS intel-compilers-2021.1.2.eb -x | grep MODULEPATH
    prepend_path("MODULEPATH", "/home/alanc/.local/easybuild/modules/all/Compiler/intel/2021.1.2")

@boegel I think we are hitting API limits on GitHub or something. I've rerun these tests twice now and which ones fail is a moving target but seems to be related to GitHub:

easybuild.tools.build_log.EasyBuildError: 'Failed to get data for PR #1967 from easybuilders/easybuild-easyblocks (HTTP Error 403: Forbidden)\nPlease check PR #, account and repo.'
