Actually for my processor (0x000306d4 / i5-5200U) this release (20171117) only
contains:

050/001: sig 0x000306d4, pf_mask 0xc0, 2017-01-27, rev 0x0025, size 17408

I find it weird that the Intel release from 2017-11-17 doesn't contain a
microcode file supposedly released on the same day, but it seems to be the
case.

Not sure which distribution you use nowadays but Henrique just pushed a
microcode update to Debian with some collected microcodes:

https://tracker.debian.org/news/899110

Obviously it lacks a *lot* of processors (especially pre-Haswell).

Agreed, but I'm not sure who can provide the information.
