Indicate that a file is maintained in the Gutenberg repository. #52015
Description
Creating this here rather than Trac to capture the views of Gutenberg contributors more easily.
What problem does this address?
Once files are merged to WordPress trunk, we've seen many occasions when someone tried to patch a Gutenberg-maintained file on Trac, and the mistake is not known until someone comments to correct the mistake. As Gutenberg-maintained files appear in various directories in the WordPress repository, this becomes less clear and requires closer examination to identify the correct maintenance location. Some files may later be maintained in the WordPress repository, so a "handover" of sorts can be missed.
What is your proposed solution?
It would be good if we could indicate that a file is maintained here rather than in WordPress trunk. Possibly, when merging to the WordPress repository, a @subpackage Gutenberg file annotation or a banner like /* This file is maintained in the Gutenberg repository. */ could be used. Hoping to gather ideas from others on this though.
