No, I actually agree; we can certainly still improve on this. Maybe by
transforming it to base64 or similar, so it's clear that it's just an
opaque identifier. I wasn't defending the current implementation, just
trying to explain the current situation and some of the subtleties of it.
(If I remember correctly, it was a bug fix late in MAAS 1.9. Originally the
VID namespace overlapped completely with these identifiers, which could
have been complete chaos and confusion.)

Yes; well, that's what the ISC DHCP server calls it, so MAAS doesn't really
have a say in the debate. (Correction: the configuration item is
"shared-network"; I didn't recall correctly.) There was no forcing function
for the auto-creation; it just so happened that this ISC DHCP concept lined
up nicely with VLANs in MAAS. Both models describe a Layer 2 network and
its associated DHCP-enabled interfaces, subnets, and ranges.
