Lens aberration correction files

[SierraDon]

I recently downloaded from the Canon website the current version of the lens aberration correction files into my EOS utility program.

Question- not all my lenses seem to have correction files. Is this because these lenses do not need correction?

These are the lenses which do not have correction files
Most of these are NOT new lenses---

EF-s 24mm f2.8 STM
EF-s 10-18 f4.5-5.6 IS STM
EF 50mm f1.8 STM
EF 16-35 f4L IS USM

Am I missing something? Why can't I find correction files for these lenses?

How can I find out if correction files for these lenses will be available someday?

Thanks!!

Don
