Hi @josemaia. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

while i'm looking at this, maybe this is a question for @stevehipwell as chart owner or @jkroepke who originally made the table - does the support matrix list make sense to maintain here as is? a lot of sources are not covered (e.g. httproute, gateway...), which confused me when looking at the chart as my first contact with external-dns docs. It seems like a pain to maintain this list, especially if the plan is to move stuff out of tree.

As I know, it was requested as comment on the implementing PR.
