Support for "UID" RDN in X509 Subject Or make literalSubject feature GA instead of being an alpha feature

Hi Team

I want to check if we can have support for "UID" RDN in X509 Subject Or make literalSubject feature GA instead of being an alpha feature.
I have a use-case where we need to support UID in the certificates issued by cert-manager but current Subject field does not have a UID parameter.

Subject field only supports below parameters, Can we add support for UID here.
subject:
properties:
countries:
localities:
organizations:
postalCodes:
provinces:
serialNumber:
streetAddresses:
source - https://github.com/cert-manager/cert-manager/blob/master/deploy/crds/crd-certificates.yaml

I see that certificateRequest CRD already supports UID possibly to support the literalSubject way, Can we add the same in Certificate CRD ?
source - https://github.com/cert-manager/cert-manager/blob/master/deploy/crds/crd-certificaterequests.yaml

Issue created - #6527

If above is not possible due to design, Can we have literalSubject as a GA feature, currently entire feature realization is dependent on an alpha feature hence there is a hesitation to adopt cert-manager for this and look for alternatives.
