[Meta] Known problems with current diffs
Context
In the context of the New Diffs (&11559) we'd like to identify the known problems, issues and proposals related to diffs across GitLab so that we can take them into account when discussing the new architecture.
Let's use this issue to highlight them, since we don't want to detach them from their respective Epics.
How?
Comment below the list of issues you're aware of.
At some point, they'll be collated and moved to this description.
