If there is one thing I want to absolutely avoid, it is to split the
userbase into many pieces by giving sticky configuration variables, so
the above argument is not a good starting point.

I wasn't talking about the name at all.  What is _funny_ is the semantics.

A "by default unsafe" configuration introduces a need for an option to be
extra careful only when matters, but "an option" to be extra careful by
definition is easy to forget, so it is no longer a safety at all, iow,
people who want "by default unsafe" will get "always unsafe".  And it
probably is perfectly fine because to them, forgetting to add 'add -N'
entries is not a mistake at all, but always is a deliberate act.

Another thing I am somewhat worried about is if there are existing scripts
that create commits and relies on the current "we cannot commit because
the final contents is not known yet".  I didn't check but for example how
well does "git stash" work when the default is flipped to "just ignore"?
