I see only signs of rudimentary intial design which predates
eldoc-...-multiline-p, composition, Flymake...

See subject line.

Maybe you would, you can adjust it. I'd rather not change more defaults
than the one suggested in the subject line.

It's similar to `help-buffer`, but also switches to the buffer when
called interactively. I don't see anything odd in that, in Emacs terms.
The command pops a window to *eldoc ...*, a less restricted view into
the continuously composed results of ElDoc collection, the echo area
being a much more restricted outlet. In the future, there could/should
be an arbitrary number of such outlets: windows, frames, tooltips, some
more restrictive, some less, some more interactive, some less.
This is beyond the scope of this bug, though.
