It's not just me calling it subjective; --subjective is literally
another name for the same switch which enables checks that are
specifically *not* part of the coding standard.

By all my means use it on your own patches before you submit them if
you agree with all or some of those checks, but I doubt all that
open-parenthesis re-alignment is going to expose any major issues. ;)

It does add noise, and makes code forensic and backports harder though.
