When making compatibility decisions, it's worth remembering that
pre-packaged software (let alone the open source subset of that) is only
the tip of a very large software iceberg that, as far as I am aware, still
consists mostly of custom purpose specific code written for particular

In this case, I think the vulnerability argument is strong enough and good
use cases rare enough to justify turning dependency link support off by
default, but it should be easy to turn back on in at least pip 1.5 as a
risk mitigation strategy.
