out of curiosity, will this work with OWNER_ALIASES file also?
e.g., like this one:
https://github.com/kubernetes-sigs/gateway-api-inference-extension/blob/main/OWNERS_ALIASES

[Jooho]

Yea I think we can use it. I added the file

@Jooho - thanks!
While you're making changes, can you please also ensure that files have a trailing newline?
GH seems unhappy with the current end-of-files.

@Jooho merging is blocked due to commit signature not verified.
can you please handle this so we can continue with merging your PR?

[Jooho]

@nirrozenbaum I rebased and amened :)

[nirrozenbaum]

@Jooho hate to nag, we required verified signatures. your commit is signed but your signature is not verified.
can you please make sure you have verified your signature in github settings?
see for example the other merged PRs, all with verified signature.

[Jooho]

@nirrozenbaum oh.. right my gpg key was expired before. I extended the date so now it should show a verified mark.

[Jooho]

interesting.. it was gone again after a few mins.. let me check it again.

[Jooho]

I hope that this time it works

[Jooho]

Ok, I figured out what caused the issue. When I rebased via the GitHub workflow button, the Verified badge disappeared, so I did a rebase first and then amended the commit again.

[Jooho]

By the way, I don’t understand why the workflow isn’t triggered, even though this isn’t the first PR.
