FWIW, I agree with Thom on this. If we do it as you suggest, I
confidently predict that it will be less than a year before we seriously
regret it. Given all the discussion around this, it's borderline insane
to believe that the set of parameters to be passed to command triggers
is nailed down and won't need to change in the future.
As for special coding of support, it hardly seems onerous when every
language that has triggers at all has got some provision for the
existing trigger parameters. A bit of copying and pasting should get
the job done.
