Why on earth would you relegate this to the wishlist?
This is about possible loss of user data.

I provided the fix, which takes 5 seconds to implement.
What's the problem?

Am I wrong that `write-region' does not provide for backups?
If not, then this is clearly a bug, and a pretty serious one, IMO.

bookmark.el even provides a user option, `bookmark-version-control', for
deciding whether and when to make numbered backups of the bookmark file.
AFAICT, that cannot possibly work if `write-region' does not create backups, as
is apparently the case.

FWIW, I made the same fix in Bookmark+.  I just think vanilla Emacs should
benefit its users as well.

Please read the bug report again and reconsider.  Thx.
