+{{/* TODO: RemoveIssueRef: the Issue.Ref will be removed in 1.24 or 1.25 if no end user really needs it or there could be better alternative then.
+PR: https://github.com/go-gitea/gitea/pull/32744
+
 The Issue.Ref was added by Add possibility to record branch or tag information in an issue (#780)
 After 8 years, this "branch selector" does nothing more than saving the branch/tag name into database and displays it.
-So there is a plan to remove it:
-* Only hide it from the UI in 1.23, and collect feedbacks.
-* If nobody complains and explains how to use it, remove code and drop database column in next release.
+
+There are still users using it:
+* @didim99: it is a really useful feature to specify a branch in which issue found.
+
+Still needs to figure out:
+* Could the "recording branch/tag name" be replaced by other approaches?
+	* Write the branch name in the issue title/body then it will still be displayed, eg: `[bug] (fix/ui-broken-bug) there is a bug ....`
+* Is "GitHub-like development sidebar (`#31899`)" good enough (or better) for your usage?
