Exactly! Since the brakes are manufactured in Germany (rather than the far East), it's super expensive to buy them, ship them separately to Taiwan for assembly on the bike, then have the lot shipped back over here... so on budget bikes like the Mission, even with extra V brake adaptors it makes a lot of sense to use Vees to keep costs down. Vees can work really well when set up correctly, but you would need different adaptors, boosters, new pads, blah blah, so a set of hydraulic brakes is a good bet (especially given the range of spares available).
Yeah, very simple but very effective, you just have to be *reasonably* careful with bolt torque since the thread is M5 and can pull out if you go nuts with the allen keys.
