i've just upgraded to 14.10, and i see that linux-image-generic now lists thermald as a dependency. is this really a genuine requirement now, that without which a computer cannot be used?
can this be listed as a recommended or suggested dependency instead, so that it is not forced to be installed on computers which have no use for it?

We've moved to the intel-pstate driver by default for 14.10 which is an improved frequency scaling driver. On some hardware we've had evidence of this pushing the CPU a little harder and some machines were running hot, so we've also included thermald to stop thermal overruns.
Also, thermald has proved useful on 14.04 on some i7 based laptops that have poor thermal designs, buggy thermal trip data, CPU thermal paste issues or broken active cooling (such as fans). These machines have normally shutdown because of overheating. Thermald kicks in passive cooling to prevent thermal overruns on these broken machines.
However, it would be useful to uninstall this, so making it recommended is probably the best option.
