RE: Should delete-window switch to next buffer when there is only one window?

Put it another way, perhaps: Define your own command (i.e., with a
different name), and remap `delete-window' to your command, for
(your own) interactive use.

Two points are important here:

1. `delete-window' is an Emacs function used in many places.  It
is not just a command, and it is not invoked only interactively
(e.g., via `C-x 0').

2. Try it out on yourself before suggesting that Emacs adopt it.
Use it for a while (months? years?).

These are two things to keep in mind whenever you have an idea
about changing the default behavior of some command.
