Same here, technically a breaking change, but not sure if this component is ready for v1.

Definitely makes sense. I’ll be releasing this as v1.0.0 while also bumping the actual kgateway version to v2.4.2.

According to the compatibility matrix, the least supported version of GWAPI is 1.4.

I also ran a successful migration test using kgateway v2.4.2 with the separate GWAPI component on one of my kgateway enabled clusters. It was a smooth transition.

I don't really care in this component, but in general, the version bump clearly should be a separate PR with label dependency.

With this change, the PR clearly doesn't check the box "PR contains a single logical change (to build a better changelog)." anymore.
