Yeah, this brings up a worrying aspect of this idea. I don’t see ANYTHING wrong with either of your screen shots IF you never lost out on progress.
We’re a fairly obsessive group, and I do not want to put something out there that’s going to send people down a useless path of “cleaning up all their activities”. I can totally understand snapping an activity because some Nodes were missed (I haven’t forgotten about User Setting: Hard Mode) but it would be such a monumental waste of someone’s time to go and snap activities just to “clean” them up. Not to mention how much that would cost me. 
Edit: I do notice in the lower right corner, there’s an activity that crossed over Memorial Dr & went into the water then came back - I can understand wanting to fix activities like that as well. Oh, and the activities where you forget to stop tracking and then drive across the county - those would be good candidates for editing as well.
