I agree, and I would prefer kebab-case in any way, i.e.: used-vmids

Besides that it mostly depends on if we want to re-use a common file for other
such specific use cases around VMIDs like per-{user,group,pool} reservations
(or allow-lists) of VMID ranges.

One certainly does not need to implement that for landing this series, but
might be worth use a slightly more structured format and generalized file
name to allow easier extension in that direction without new files and
only needing to look at a single file when allocating VMID.
But this can also be adapted on applying, it should mostly affect parsing
and serialization, and maybe those even not _that_ much.
