FWIW, I typically use multiple frames, and typically with a single buffer each.
Most of my frames are not dedicated, but a few are.

Nevertheless, I agree with Juanma here.  For my purposes, iconification would
always be wrong as part of the behavior of `bury-buffer'.

IIUC, Stefan also uses frames a lot, but he typically (always?) uses
(soft-)dedicated windows.  And he uses a different OS from me, so iconification
might be less annoying for him.

I would like `bury-buffer' to be decoupled from iconification.  I would like
`bury-buffer' to do nothing particular wrt dedicated windows.

Another caveat: I know little about soft-dedication.  Perhaps that makes a
difference to understanding this issue.
