That would only be the case, if you were to consider those other 
dependencies as "dangerous" as cURL. But we already depend on them. So 
if it's really the case that cURL is that much worse, that we consider 
loading it as a module... then the combinatorics should not be a problem 
either.

However, if the other deps are considered problematic as well, then the 
ship has already sailed, and there is not point for a special case here 
anymore.

Best,
