It doesn't make sense as part of cpufreq(8) for two reasons:

First and foremost, it is GPL2 software.

Secondly, it is extremely machine-dependent software.  It is
x86-specific and has a lot of different code to handle each
microarchitecture from Nehalem through Skylake.  It would be one thing
if this was a small table, but it is 5000 lines of code.
