No argument from me here. However, I completely broke sparc by
applying it so I needed to post an ASAP fix with the least possible
impact. A followup patch for v3.2 would have be written to generalize

Rolling the assigned ids into the alias list was a convenient & cheap
way of making sure the id assigned would be unique, but fair enough.
Shawn and I will talk about implementing a better solution.
