Customer was reasonably happy to stay but gets prompted to look elsewhere
since the main pain of moving is one he's going to hit anyways. You can't
argue this as good for the ISP.

Customer is happy to stay and will - but the relationship may be soured
somewhat by the renumbering process. There's certainly a LOT more scope for
something to barf and a someone to need blaming then for someone to say
"gee thanks for making us renumber".

Customer decides the pain of renumbering is such that he decides to mocve
to one of the really big boys so he never has to do it after this once.
Maybe he's wrong and will have to re-address the issue at some point but
even so some people may take this not entirely unreasonable attitude.

I fully agree that all these people should be able to accept and handle a
renumber without too much hassle but that doesn't prevent the fact that
there's at least some scope for the customer winding up leaving the ISP
over this issue and no scope for the opposite. Thus growing ISPs which have
to renumebr more often are going to be disadvantaged.
