A slight disadvantage of this approach is that the resulting 
incongruence between the client and the API is obfuscating.  When an end 
user can make accurate inferences about the API based on how the client 
works, that's a form of transparency that can pay dividends.

Also in terms of the "slippery slope" that has been raised, putting 
small bits of orchestration into the client creates a grey area there as 
well:  how much is too much?

OTOH I don't disagree with you.  This approach might be the best of 
several not-so-great options, but I wish I could think of a better one.
