I like your comparison with browsers. In many ways, the only way to know for sure is to test in the desired terminals and figure out what works on all of them.
There's some "new" stuff as well (90's), like SIXEL graphics. I was surprised by how broad the support is (however not that broad to count on it).
Yeah. Even more recent efforts are the efforts to bring powerful features to terminals. Kitty in particular came up with many of them and had to deal with ncurses refusing to support it.
