Ant+ Fitness Profile Support...

I want to track more data when I'm using indoor equipment... however there are few indoor fitness machines that support ant+ at all - and those that do only seem to support the ant+ fitness profile which presumably is a bundled data set including speed cadence power etc...

It would seem practically all the current models do not support this fitness profile - how do i register a request for this.

surely supporting an extra ant+profile is just a bit of code and requires no extra hardware.
