Subject: bug#65864: [PATCH] Add option to save a buffer without running save hooks
Date: Mon, 11 Sep 2023 18:28:59 -0400

Do you have concrete examples, to helps us assess what's really at stake
here?  Maybe there are other ways to look at the problem :-)

"without running any save hooks" at all really?  Like without running
`write-contents-functions`, nor `write-file-functions`, nor
`write-region-annotat-functions`, nor `make-backup-file-name-function`, ...?
How 'bout the file-name-handlers, then?

Maybe `write-region` would be a better starting point than `buffer-save`?

Hmm... sounds iffy.  I generally prefer ordering a plain burger than
ordering a "cheeseburger but hold the cheese" :-)

IOW, provide *another* function which performs the core operation.
[ And we usually do that.  ]
