I like the idea, but in some years there would have to be so many caveats to the detachment allowances that it probably just isn't worth it to make so many rules. For instance in 2007, an alliance could probably have detached enough 'stuff' in their own homezone to make it extremely difficult for their opponents to get one of the tubes lying against the wall. The same goes for setting something up to get tubes from the slot, but to a much lesser extent.

Even in a year where it would seem like a simple addition to the rules, there's still the issue of people tripping over small robot parts duing field reset, teams using detachments for defense, etc. I think one of the only ways to do it without making the game more hazardous or boring to watch is to put zones for each alliance that allow the detachments but disallow the opponent robots. Hmm, maybe I haven't let my imagination run with the idea enough yet.
