This has changed somewhat recently. Reportedly SpaceX is the one who
shelved development of Dragon V2 vertical landing. The reasons for this
aren't terribly clear, but there are hints from SpaceX that this is
because they've decided to change the (Mars) landing mode of their
(eventual) Mars vehicle.

Also apparently NASA weren't happy about cargo flights being used for
testing powered landings.


Why would they care? They get their cargo on the way up, not the way
down.

Because Dragon is the only way that NASA can get things like EMUs back
to earth for refurbishment. There have been articles on how few
functioning EMUs are left. Sorry for the word-wrap on the cites:

I think it's funny that NASA lets astronauts ride on Soyuz,
which relies on power at landing on dirt for them to survive, yet is
being obstructionist to safety certify Dragon V2 for fully powered
landings on dirt.

That's the rumor. Another rumor says Dragon V2 propulsive landings are
being dropped because SpaceX is going to be changing its landing mode
for Mars missions. I'm not sure how much stock I put in that, but we'll
just have to wait and see. SpaceX isn't afraid to change directions
when something isn't working out or when another more promising approach
surfaces.
