Ability to choose multiple post types for a reaction
Currently, reactions are limited to either belonging to all or only one post type. This is inconvenient for when one wants to have a reaction that applies to more than one post type, but doesn't apply to all post types (the example that prompted this was the [citations needed] reaction on L&L, which I would like to apply to both answers and articles, but not questions)
The reaction model itself enforces "only one", so this isn't just a matter of changing a selector to a multi-selector in the UI. (Hence the "ruby" tag instead of the "html" tag.)
From the discord some time back (June 29th)
Database reason. Querying for one v. all is way easier and faster than querying for many (one column v. one reference table)
Unless anything has changed since then, this can probably be closed as not planned
