So if a *customer* asks Sprint, either directly, or via a
community like 1755:12xx (see whois -h whois.ripe.net AS1755),
is this "unilateral" on the part of Sprint?

If it were a paying customer who indicated that Sprint should
prepend, do you feel Sprint should be obliged to inform all
customers beforehand?    Is your answer different in the case
of non-revenue connections ("peers")?

How should this be done in the event that "prepend-request"
BGP communities are being used by a network connected to
Sprint, given that the other network may set or not set
the attribute for any given prefix at any given time?

Welcome to the Internet, it has routing complexity growth over time!
