The current default is convenient if you work on a "cp -al" copy of a

I'm sure it's more convenient in some cases, but I don't think that
outweighs the trouble it can cause.  When it's clobbered links you
normally have no indication, and it's likely to lead to obscure
problems.  It took quite a while to discover what had happened in the
case that prompted this.

Indeed.  The very first thing I put in every Emacs installation's default.el
file is

(setq backup-by-copying-when-linked t)  ; preserve hard links to original file
