In my experience, in most cases default behavior does the right thing,
and as I have commented

And I think having default behavior to be safe in many cases is already
very notable. AFAIK in UNIX almost every package maintainer need to write
some script manually, so it’s pretty reasonable to shift the responsibility
of “100% safe” to package maintainers.
