FWIW, the repeater freq coordination group in my neck of the woods
will assign &/or coordinate a freq pair to a "paper repeater" with
coordination dropping in 90 days if it doesn't become real. I think
this is done to facilitate setup by the repeater owner. Wouldn't be
nice to have a system tuned up and ready to go on an uncoordinated
pair that turns out to cause interference with coordinated systems.

Might have to go that way, with the uncordinated pair first. The
cordinator in my area says they try to avoid "paper repeaters" and
suggest I get equipment up and running first. ;-) But they did say
that I should be able to get one for my area.
Lots of good information in this thread.
