My own engine used to be a single-game stack. Now there are more than 40 games written with it out there (and only one of them with its code written by someone else than me). It's not an IDE at all, just a bunch of (often intentionally leaky) abstractions on top of existing libraries. It comes with a tiny external editor written in PyQt that produces animations that can be consumed by the engine (which is optional, as they can be created by hand too), plus a bunch of scripts that use Docker containers to effortlessly cross-build it to several platforms. I really don't care about other people using this engine. It's not for them, even though it's public and FLOSS. It's a tool for me (and people I work with) to make it easier for me to write my games the way I want to write them. I wonder what the article's author would call it ;]
