Yes.

(add-to-list 'display-buffer-alist
'("\\*shell\\*" nil (inhibit-same-window . t)))
(pop-to-buffer-same-window "*shell*")
Have you ever read sections 29.15.5 and 29.15.6 of the Elisp manual?
These contain numerous examples of how to add the 'inhibit-same-window'
action alist entry to do precisely that.

Then we have to leave 'pop-to-buffer-same-window' alone too.
'pop-to-buffer-same-window' is the customizable version of
'switch-to-buffer'.

There is no such equivalence. Think of 'pop-to-buffer' as a proposal.
It's what the writer of an application considers the best choice for
fulfilling its customers' needs. 'display-buffer-alist' is the user's
answer for dealing with that proposal.

Every second specification I write fails initially.

We can add that to the manual - as soon as we think it's good enough.
