Well, I do agree with what you're saying, maybe it could be phrased in a less aggressive manner? Shove should certainly be implemented as an action, or as one of your attacks for those characters with Extra Attack. I also think it should be able to be used to push to prone, it would add some variety to Extra Attack. And while I'm O.K. buffing shove to about ten feet for 'fun' reasons, the present distance one can shove a target is ridiculous.
The Reaction system is still in it's infancy though. A host of reactions have been left out, the Attack of Opportunity is a glaring exception, they're presently expecting you to toggle it off if you have a more important reaction pending. I think Sneak Attack could benefit from the reaction system, just like the Paladin smite ability, allowing one to decide what attack you applied Sneak Attack to. Of course, Sneak Attack wouldn't actually consume one's reaction, the system would simply function as a vector like the Paladin's smite. Reactions like the Shield and Absorb Elements spells are sorely missed, yes.
