I don’t understand a word what you are saying, but that is entirely my fault. I understand, though, that you are counting software processes and I have no idea how these translate into hardware recourse requirements. Could you elaborate?

I understand that this can be a disadvantage from the perspective of a (commercial) hoster because your clients wont have access to /sidekiq on their respective sites and if you give them access to the mastersite they will possibly see more than they want or should see, right? But if all sites are mine, it probably doesn’t matter, right?

Very important point, thanks for bringing that up! However, provided that all installed plugins have a switch to turn them off, it doesn’t really matter, does it?

Wait, the only one of my instance where I did something with a `discourse.conf` file is the one where I have discourse behind a reverse proxy and there is nothing about email in that file.

How do I know which ones? Trial and error? Or, since this also about future compatibility, what type of plugins are likely to be incompatible?
