As a sole developer I have to prioritize features due to the time constraints. While I would definitely like to implement support for everything you listed, this would be a lot of work. For example with terminals in general, it can be very difficult to get one up to the standards of other comparable terminals. By delegating everything to other terminals, I can make the development easier.
So in the long term future this might be added. But that also depends on the project’s trajectory going forward
