Yes, I remember the time when radio 4, for example, only turned it on when it
was broadcasting stereo material - thus giving better reception to many the
rest of the time! (Especially since many stereo radios don't have a "mono"
switch.) I genuinely don't know why they stopped doing it: I can only assume
the reason was financial (including technical-financial, i. e. catering for
the control signal, and the time of the person whose 1/100 of a job it was to
monitor and control it, was exceeding the cost of the extra power used), added
to a small contribution from the thought that some people would think there
was something wrong with their set if the red light wasn't on.

I was intrigued to read in this thread that some pirates are indeed switching
to mono.

It was for much the same reasons as for switching the PAL colour burst on and off
which also used to happen for mono programmes.

Firstly, on many receivers there was a 'splat' when the switch occurred, and secondly
as described in other posts, the FM signal is often more noisy when the pilot tone
is on than not.

It was nothing to do with finance. Engineers were more important than bean-counters
in those days ;-)
