Without looking at the details, it sounds like all of them should be fixed.

But this report is only about fixing messages wrt `find-file-noselect'.

Do you disagree that it makes little sense to display messages when
`find-file-noselect' is called from a non-interactive function?  And that it is
not too helpful to find a message in *Messages* telling you only that some
(unnamed) file (perhaps in a dolist that handles 12358 files) was
write-protected?

The priority of fixing bugs is for Emacs Dev to decide.  And this one has been
around a very long time, so it is probably not the most important.  But in any
case, it is a bug, no?
