Verification

[x] I ran brew update twice and am still able to reproduce my issue.
[x] I have supplied my brew doctor output above and it seems unrelated to my issue.
[x] This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.
[x] I did not use AI/LLM to create this issue, or I disclosed the tool and model used; I will answer maintainer questions myself without AI/LLM.

What were you trying to do (and why)?

The autobump CI ran into a formula with patches in the stable block, removed them and then couldn't create the PR because it left a stable block with only a URL and shasum.

What happened (include all command output)?

What did you expect to happen?

I expected autobump to create a PR that failed the style check, or kept the patches. Since knowing about the update is more important then having the patches cleaned up.
