Hi!
That is by choice. We have an issue:
https://github.com/stratis-storage/stratisd/issues/729.
The hyphens are an annoying artifact from a particular version of the UUID spec, where the
hyphens separate different regions of the UUIDs which have different meanings. For most
UUID specs, the regions are totally spurious. We can document that this is our decision in
the design docs, if we do not do so already.
