Recentf is quite an old package, and it seems its users are happy with
the way it records recently opened files. Perhaps this means there
are not many places where find-file-noselect is used for internal file
processing (i.e. not intended for the users to know). In those places
where such processing is required, a more preferable way is to insert
the contents of a file into a temporary buffer.
While I tried to run the code which uses find-file-hook I sent earlier,
I noticed that often it adds too many file names to the history, even
the files opened for editing (there were no file names left from internal
file processing at all in my test). For example, I don't like that
`next-error' adds every file it opens from the grep buffer. Also I
don't like adding files visited in read-only mode by dired's "v" key.
All this means that the question what file names to add to the history
is rather a matter of personal preferences. A simple hook for
`find-file-hook' is easy to put in .emacs.
But even if this functionality will get into Emacs, I think it's
better to leave the current default behavior (with only adding user
input to the history) unchanged.
