I think that's why #joinSeparatedBy: was initially only on sequenceable collection.
I mean, it is also unclear what joinSeparatedBy: would mean on a Bag with multiple occurrences, or a Matrix, or a Bitset…

On the other hand, you can always do things like
	myCollection asArray joinSeparatedBy: 'fnord'
or 
	myBag cumulativeCounts joinSeparatedBy: ', '
or
	(mySet sorted: [:a :b | a >= b])  joinSeparatedBy: ' is more than '

and be explicit on what you expect to establish the sequence.
