company-mode does use them, but with `before-string' and `invisible'
instead of `display'. Not exactly sure why.

I use them all the time for different purposes - but only for
highlighting stuff like highlighting the current line of the selected
window, or give a visual orientation when scrolling a window. It's
probably quite unusual to change the displayed text of a buffer on a
per-window basis.

I think the more advanced features of the display engine are generally
under-used. Maybe because there aren't as many users from the front-end
side of things.
Btw, I'm trying to implement variable width right/centered paragraph
alignment. Now that I think about it, I might also do justified text (with
varied width of spaces).

It's still in prototype stages, but the prognosis is good. And with
window-specific overlays, I can make if work even it the text is displayed
in multiple windows simultaneously

Also, wanted to ask, is there a way to use bidi display to align English
text to the right?

You can set bidi-paragraph-direction to 'right-to-left, but I suspect
that's not what you want. Editing and moving inside such text will
behave in ways people don't expect to see in strict left-to-right
text.
In general, the bidi display is not about alignment, it's about
display of bidirectional text. That is what it was designed for, so
any other uses will not necessarily produce desired results. That it
also flushes right-to-left paragraphs to the right margin is because
people who use right-to-left scripts expect that.

Indeed, the "directionally neutral" characters are displayed according to
the paragraph's main alignment. Anyway, once the centering works, adding
right alignment shouldn't be hard.

It's used in doc-view-mode, but indeed, it's rarely used.

I just used it a few days ago for something called
temp-buffer-browse-mode in my init that enables "SPC", "DEL" and "RET"
keys immediately after a temp buffer popup to scroll up/down and close
the temp buffer. (if this is generally useful I can submit it to the bug
tracker.)
