Very true. I admit I was a little sloppy in my response. If proper
welding procedures and appropriate rebar material is used (A716 if my
faulty memory serves me correct) then there should be few problems with
welding the bars directly to the beam.

Again, I probably should have said "...in the shop could be knocked
off..." so as indicate a remote possibility instead of a good probability
of it occuring. Also, I was assuming that the likelihood of the use of
non-weldable rebar could be use by accident (or not). Welding is a good
option, I just prefer to use the mechincal couplers welded to the beam.
