Was that to ensure that there wasn't more than one default action?  I 
think its better to instead clarify that in the text part of the spec vis:

"By default all unspecified threads remain stopped.  An action with no 
corresponding {tdid} shall be applied to all threads with out an 
explicitly specified action.  A packet specifying multiple default 
actions is erreneous."

Looking at the new gdbserver code it's pratically doing this now.  BTW, 
I think it gets confused by the incorrect "...;cccccccccc", simplifying 
to be strictly LL1 will fix that.

Seperator or terminator?
