I would happily use the Google Maps "share" feature, but I've yet to encounter any but the simplest of scenarios where it actually preserves the entire context of what I'm trying to share: the viewport, the start and destination, stops along the way, route choice, the time of day, all of it.

If I'm sending a screenshot it's because I want to send exactly what I see on my screen and not have my recipient's gmaps instance happily recompute a route it thinks is better or leave out the routing information I included, or switch from biking to driving directions, or whatever else.
