If you would like to productively add some input, I'd certainly welcome it. I like to learn more about this space. My own experience of course includes various terminal emulators with unset or unsupported TERMs. Of course I have of course experienced breakage.

Please note that I didn't say few or no programs use TERM. Rather, I mildly disagreed about "nearly any program," and pointed out that there are more robust alternatives to TERM.

Especially when it comes to greenfield development, it's not clear to me why anyone would use TERM rather than capabilities. In any case, I always try to leverage caps whenever I can.
