Question on the decision making process for kernel variants' configurations

Hello and greetings,
I am attempting to gain some insight into the decision making process that
goes into the kernel configuration choices selected for a given variant
kernel. I have rummaged around the Ubuntu Kernel Wiki, applied search
strings to the downloaded kernel-archive mailing list mbox, and bounced
around on the Ubuntu Launchpad - all without finding either information on
the general review process, or finding specifics on the particular detail
I'm interested in.
What am I interested in exactly? In the gcp kernel variants the
CONFIG_UNICODE (UTF-8 normalization and casefolding support) option is
disabled. This configuration option arrived via (assuming I've trawled
, and was set to unset (off).
As to why, there are two guesses I might make:
One: As the gcp kernel variant already exists with a set of known
configuration values, perhaps anything new and considered optional is left
unset, until such time as an issue is made asking for it (example,
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1849493) - perhaps I
should submit an issue?
Two: Perhaps this specific configuration was left unset per concerns a la
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-21300 - in which
case submitting an issue would probably not be fruitful? ( though I
believe the post
makes a nice case for why the CVE isn't precisely cause to leave this
And of course, the rationale might be something I have no clue at - So I am
asking if someone might point me in the right direction - either towards
the background information I seek, or perhaps specifically suggesting that
I open an issue.
My thanks, and I appreciate your time,
