I wonder a bit. iptables is fine with loading ipt_%s (mapped to xt_%s),

Of course it makes sense to use a separate namespace - especially
in light of the nf_conntrack_ prefix used by both helpers and
protos, but I'm still asking.
It is not the same point. The xt_* aliases in iptables were introduced
to keep backward compatibility for iptables (old versions try to load
ipt_* or ip6t_* modules, as they don't know anything about xt_*. Of
course, this is no longer true for current iptables versions).

Sadly enough, iptables still loads ipt_%s instead of xt_%s.
Maybe it's time for a patch..

Its needed to select the proper module, f.i. in case of REJECT.
