I can't agree more! It would certainly be convenient to be able to
use a Unicode font for an IBM 3270 or Siemens BS2000 terminal emulator,
or an ITU videotext decoder, without having to fall back to special
purpose fonts. I have over the past few days drawn hundreds of silly
Unicode blockgraphics symbols, and considering the effort, it is quite
a bit frustrating that I still can't support with my new ISO 10646
extended X11 fixed font the needs of many terminal emulators without
having to make private incompatible extensions.

Definitely decades!
