You compare now to node names. The node names have visible impact (name
of devices in sysfs and in system), is affected by DT schema (is parsed)
and should follow DT spec rules.

There is nothing like that about labels, therefore they do not have the
same rules or importance.

I understand that consistency in labels might be good thing... but also
it does not matter. The labels really do not matter, except the code
readability. pmgpio or pmgpios is basically the same readable.
