It would be sufficient to use an encoding variation which adds the bom
back on writing.

I am actually surprised that this is not done right now: I thought we
had a discussion about having the BOM-encodings early in the automatic
encoding detections.

Emacs developers are not nonchalant about having Emacs write a byte
sequence differing from what it read in (apart from where it can't help
it, like with non-canonically encoded valid texts in shift character
based encodings) in my impression, and it is one of the better features.
