We have a customer who was assigned some PI IPv4 space by Paetec back in mid-90's and who has continued to announce the blocks, even though their relationship with Paetec ended a long time ago.
Is this a common situation?
It was back in the day. It isn't any more. Most folks doing that have since renumbered.
Does the customer risk having that space reclaimed by Paetec at some point,
That depends what Paetec has to say about it. Unless the customer has paperwork to the effect that the assignment outlives the business relationship (and for how long) then it's entirely up to Paetec staff today and tomorrow.
or is it safe to assume they will continue to be able to route trouble-free for years to come?
Like all registrants, Paetec is under increasing pressure from ARIN to justify its ongoing assignments. It is not required to provide Internet services to your customer, but lack of ongoing contact with your customer is likely to become an administrative problem for them.
