Normally a transmitter is rated to provide some value of r-f power output
into a load having no more than 'X:1' SWR with respect to the load impedance
the tx is designed for. Such a load can be provided by a large number of
antennas of different directional gains, yielding different ERPs even though
the tx output power into each antenna type is the same.

One possible concern of the tx manufacturer for ERP might be related to how
well his product is shielded. But such a concern probably indicates a
rather inferior design.
