Lol, no. You can still use different font sizes, traditional controls that can also be used with a mouse (for people who don't know the shortcuts yet). Also images are possible where they make sense.

While using very common web development stacks a lot of developers know how to deal with.

I give you different font sizes, but a mouse and images are available in the Terminal as well.

I think the fancy new terminals also allow you to change the font.

Fancy old terminals that I don't see in emulators.

Look at the era of teletext. Not exactly multiple typefaces, but you could express wide, compressed, italic, bold and all colors.
