Depends.  I'd much rather have::
  yum remove (-r|-R|--recursive) this_really_cool_thing

than::
  yum remove --no-recursive this_really_cool_thing

But maybe that's just the positive me.

If it goes in /etc/yum.conf then either one could be the default.  A
setting in a config file can be scripted in a kickstart, deployed by
puppet, or set by an individual user once and then forgotten.
