For some, fitting TRVs might increase comfort! I find I am uncomfortable

Irrelevant, but in some council-run district heating schemes each
dwelling has a device on the wall that measures the room temperature and
this is used to calculate the bill for that dwelling. So the residents
drape bags of frozen peas over the device.

There are devices which measure the flow rate and temperature drop
between flow and return, to enable accurate billing for energy
consumed. They are not cheap though.
