I have used RoadGraph plugin several times with OSM data and it worked fine.
Also I tested Processing algs with projected and not projected OSM data, it
also worked for me. Maybe your points are placed too far from roads or network
itself contains gaps? In this case adjusting topology tolerance may help.

This widget was added about year ago or even later (can't remember exactly when
I made it). And of course it can be used in any Processing algorithm.

This is known issue and it is also happens for extent selector. There
are no solution
at the moment, but we (Victor and me) plan to work on it. Hope this
will be fixed before
release. Related ticket https://hub.qgis.org/issues/15680.

Well, I never thought about being on par with GRASS and don't know if this makes
sense.
