I think we should keep the current default.  While the ability to
debug both sides of a fork is a nice feature to have, I think most
people are only interested in debugging the process they started the
debugger on.  It is not unusual for programs to use system(3) to
execute system binaries, and I doubt people are interested in
debugging those.  Typically those binaries will be stripped anyway.
Setting detach_fork to off will only interfere.
