In contrast to Gerrit patches with "Bug: TXXXXXX" in the commit message, there is no "patch-for-review" tag added for Differential patches on arc diff.
Who would benefit
The tag is helpful to maintain better overview on the state of tasks for developers and product managers in workboards, like for example UI-Standardization-Kanban
Currently you have to manually add the tag, see T147612 as comparison.
Add Patch-For-Review tag when triggered trough valid commit message at arc diff.
