Thanks for the reply, Tree.  It clears it up, just a little.  I  understand 
the idea about the multi transmitter, but, isn't the category MULTI  OP, 
SINGLE TRANSMITTER anyway?  Still not sure how a 10 min rule would have  
anything at all to do with stopping a cheater, using more than one rig.   The 
class seems as cut and dried as QRP, LOW POWER, and HIGH POWER.  
But, they are the rules, like it or not!

Without the 10 minute rule - one can just use unlimited  transmitters and
operate like they were a full multi-multi.  The  intent of the 10 minute
rule (or a limited # of band changes/hour) is to  "enforce" the intent of
the category - which is that you have two stations  setup.  

This is a necessary evil for multi-single or two  transmitter categories.

The recent DQs in the CQ WW were a result of  people who changed the times
in their log - so that it complied with the 10  minute rule - but not the 
intent of the category.  They were  essentially unlimited multi-multis with
rubber clocks.

In the case  of single-ops - there is resistance towards limiting the 
operator with  this rule.  It would basically prevent the practice of 
QSYing  multipliers to different bands - and also second radio operation
where QSOs  are found on a second band while running on another band.
