Some Apps are in meta files (releases.json, dates.json, readmes.json and colors.json) but missing in `apps` directory

[rustdevbtw]

I tried to create an API which fetches app list from meta files and then get's the app's info by fetching the .yml file from https://raw.githubusercontent.com/electron/apps/master/apps/${app}/${app}.yml. But I got many 404 errors in the API. When I tested some of them manually, I saw that many apps are in meta files but not in the apps directory. I found no Pull Request for removal of those apps (for example, ffftp).

I made a list of Apps that are missing from the apps directory. Total 382 Apps are missing.
Here's the list:

I found #1987 PR
Is it related to that? And why the meta files are not updated then?
