@gizas I didn't expect changes would be required in kibana, should the change only target the next release 8.5.0 and not 8.4.0 and 8.3.0?

[gizas]

I would say to exist also in 8.3 and 8.4 in order to be aligned.

FYI I see them in the automatic PR https://github.com/elastic/kibana/pull/138713/files that was created from here . Still not merged
