That would be overkill. those are only Abort engines. 

That's what I thought.
But does it bring the useless abort motors to LEO, or uses enormous T/W to, say, deorbit?..

(As its RCS look like enough for deorbiting.)

Both SpaceX and Boeing chose an Abort system that stays with the Capsule all the way to Orbit for some reason. But no i don‘t think these engines are ever used on a normal mission.

The reason is it eliminates another separation event. Tractor systems have to be jettisoned after they are not needed, and any failure in that system is a profound problem.

Because reuseability.

Since SpaceX is now not going to fly Astronauts on reused Dragon 2s it is kinda pointless to have reusable Abort system.

I think they were talking about transitioning cargo to the new vehicle, and they might reuse them for some commercial stuff, if anyone wants to buy a ride.

i‘d like to see the non NASA astronauts they are flying to space

I think space tourism is still on the table for SpaceX. Great way to make some quick cash before Starship comes. Its max capacity is 7, so 1 pilot and 6 tourists is doable. 

Let's say 1 full day in LEO without docking. Sounds fun.

Who would be the pilot? Do they train their own Astronauts?

Virgin has their own astronauts-pilots, can't see why SpaceX won't be able to have their own. They'll have to anyway, for that Starship mission, Moonshot i think?

I don't know exactly who, but they've been training 2 NASA astronauts for Demo - 2, so they do have quite a bit of experience in that department.

They can sell it as a second-hand.

What pilot? Ripley?

NK would be interested, too.
Also, they could test limits of its reusability.

And Fёdor. They are going to send him to ISS in 2021+, so they can marry.

The RS-88 engines can gimbal to angle through the vehicle COM so I think it is probably pretty likely that they can be used for changing orbit and deorbiting, though they may want to use RCS thrusters for more precision. 

The original RS-88s used LOX/ethanol but these have been modded to run on hypergolics. Boeing won't tell us what their Isp is because apparently they have ITAR heritage.

They will reuse Dragon 2s for cargo delivery, which means cargo will now have abort capability. Dragon 1 is officially deprecated; they will continue reflying reused Dragon 1s until they all retire.
