"We could just define the functions and not choose
a default binding."

Yes, that's preferable to sacrificing `C-x t' as a
default binding.

Define the commands.  Define keys for them in a
keymap.  But don't bind the keymap to any prefix
key by default.

Yes, let users decide.

Define a keymap variable, to make it easy to use a
prefix key, but don't bind any prefix key by default.

What's wrong with that?

How about serious supporting arguments?
Have there been any?

FWIW, I don't like the idea.  There's nothing
"free" about `C-x t'.  It doesn't have a default
binding; that's all.  And that's a good thing.

Let users and libraries have it, without them
needing to override standard Emacs default
bindings.  Likewise, other `C-x' keys (`C-x 6'
etc.).

(Just one opinion.)
