Changing the KLT release config to lifecycle operator is not really accurate IMO.
lifecycle operator is just that folder but KLT is everything else in the repo and maybe also the umbrella chart in the future. So those will in the end be separate entries in the release-please-config.

Hmm yes you are right, it is just one part and KLT is the whole toolkit incl. metrics-operator, cert-manager etc. What naming would you then suggest? I do not see the problems around umbrella charts and you have definitely more insights there. The "lifecycle operator" monorepo should not include lifecycle-operator, scheduler, python-runtime and functions runtime, as that are the pieces that need to be installed to have the whole package working.

[mowies]

you could just leave it as klt like it was before

lgtm, as discussed let's wait for @mowies approval due to the renaming work that's currently going on

LGTM!
