I agree (to the extent that I understand it).
I've said as much several times before.

It provides a comprehensive solution, which is
necessarily complex.

My complaint is that we don't also provide some
simple to use constructs for simple use cases.

In particular, I've very glad we still have
the `special-display' stuff available.  Simple,
great for some simple use cases.  But when the
new, comprehensive solution was created (a
_good_ thing), Emacs simultaneously deprecated
`special-display'.  We _have_ it, but we're
discouraged from using it.

That deprecation I object to.

But I do appreciate that it's still supported.
I hope it will continue to be so.  And I still
have hopes that the deprecation will be lifted
from it someday.  Users are in general unaware
of it now (it was removed from the manual etc.),
even though it's very good for the simple use
cases it handles.

Thanks for pointing it out.  I'll take a look.
It's not that new apparently - it's in Emacs
26.3, at least.
