Like I said that's how TRV based systems work.
The room stat has to be in the warmest room and switch the system on even if
only that room wants heat.

No they don't. There is nothing to stop a thermostat being located
*anywhere* where it will receive the appropriate amount of output from
the heating system. Lots of thermostats are located in hallways with
no TRV's on the rads and controlling to a much *lower* temp than the
main living areas. As long as the rads are sized correctly, the
thermal losses through the structure are not wildly different, the
outer doors are not opened on a too regular basis and doors from an
area with a higher desired temperature are usually kept closed then
they function well.
