The DADA Curse Implications

Whilst its not explicitly confirmed it is strongly implied that DD 
knew about the one year curse on the DADA position and has done for 
a while. This means that he knew whomever took that position would 
(for one reason or another) be unable to keep it longer than a year. 
Furthermore there was a strong chance (each year) that the teacher 
may even lose his/her life! This has huge implications.

I can see why this wouldn't bother DD in the case of Lockheart and 
Umbridge but what about Lupin and Snape? This could be proof that DD 
expected Snape to do what he did (he certainly must have expected 
that Snape would no longer be DADA professor at the end of the 
year). Perhaps it is also why he was reluctant to give it Snape for 
so long. 

But what about Lupin? Was he at least warned? Possibly DD guessed 
that his leaving would be related to Black's escape and/or his being 
a werewolf and not the death of Lupin but still, the fact remains he 
was 'outed' as a result, and we were quite lucky that that was the 
full extent of his suffering. I can see Lupin agreeing to take the 
risk if he was warned but otherwise this seems quite dangerous to me.

I am sure there are further implications of this, too.
