Not all their IDEs. Jetbrains Rider has specific modifications that are integrated into the IDE for .NET software development that aren't available in even in IntelliJ Idea Ultimate. The same goes for CLion, the C/C++ features are not available in any other of their IDEs. Though, I think those are the only two IDEs where the the features provided are not available as plugins.

I wonder when this started, I was under the impression that Ultimate had it all, but maybe that was either never true, or only when I last had to petition for the team to get it (10 years ago). Not even sure either Rider or CLion did exist back then.

For Rider, it's because they built ReSharper (a Visual Studio extension) before Rider, and then built Rider to make it use ReSharper as a back end without Visual Studio, while still using the IntelliJ platform.
