I can't imagine why PoE WOULDN'T work on Cat3 cable, the pinout and
colour coding is the same as Cat 5 and I doubt there is any high speed
signalling for the PoE negotiation. It is just the wire gauge and number
of twists that change. Cat3 was designed to run 10Mb ethernet but 100Mb
is dodgy. Also note that plain Cat5 was designed for Gigabit, it's just
that 5e is more reliable at high speeds on longer runs.
Is the obstacle to using Cat3 more in the sales commission of the cable
contractors than in any inherent physical property of the cable?

For a long time now the common wisdom is that a big obstacle to re-using
Cat3 cabling for VoIP phones is that PoE is not supported on Cat3.
