Ah. I thought this as covered by the entry in dt-core.yaml

If not fair enough, though is this flexible enough to cover that it can
exist at device level and in a channel node?

If so lgtm

I'm guessing you already know this but I hit it during testing.
dtschema/main + ruamel.yaml 0.17.24 and later seem to be broken. It installs
fine but...

AttributeError: module 'ruamel.yaml' has no attribute 'YAML'

    rtyaml = ruamel.yaml.YAML(typ='rt')   

I've worked around this by setting a max version at 0.17.
Only change in ruamel.yaml between those is:
https://sourceforge.net/p/ruamel-yaml/code/ci/4309006902d2453399588f4ddccfb3fc460e1eba/

My python is terrible so I'm not looking into this further.
