It's got some similarities with I2C and SPI but there's some important
diffferences too, in terms of software it's got many of the features of
things like USB - there's data channels, bus wide clocking and a probe
mechanism.

In this case the IDs should definitely be different as there's IDs in
the hardware which drivers ought to be able to bind to (in theory the
bus can be hotplugged).
I do agree that there's room for some code sharing with the
non-probeable buses.
