coan.net: But surely the difference between "random position for each game", and "random position repeated over the whole tournament" is way smaller than the difference between "one game match" and "10 wins match" the tournament creator can make for the final match anyway. Not to mention a difference between "max 4 people per segment" and "max 20 people per segment".

IMO, only three kinds of tournament editing make sense:

1. No editing allowed at all
2. Only allow editing things that don't affect game play (name of the tournament, days after deadline, early start, add/delete game types)
3. Edit anything (time control, match types, number of participants/section, autopass, etc)

Brainking allows more than 2), but doesn't allow you to edit everything.
