Marking this as blocked by #6587. I want to ensure we have a clear stance on the future of our MPTT approach before implementing it for any more models.

With #6587 slated for v3.5, could we slate this for v3.5 or v3.6

[ryanmerolle]

Not to open Pandora's box, but would we look to set a uniform setup for IPAM roles as well?

If we get it implemented, sure. I think right now we're leaning toward #11421 as an alternative approach, but either way we still need to provide viability to replace MPTT.

Unblocking this as it doesn't seem like we'll be replacing MPTT anytime soon.
