TS here. I sure hit a nerve, I guess.
Totally agree that a more agile approach would be desirable.
But like Jack, I'm not sure that "integrating the MRA ecosystem" would be the best direction of travel. For me the GPX ecosystem is key. See my initial reply at the top of this thread. We need to support a variety of devices, tools & apps and better GPX support is the way to do that.
Let's not forget that this is where MRA was first successful: a tool that let you plan routes which you could then export to Garmin, Tomtom, etc.
(For comparison, take a look at gpx.studio, which I think was hacked together by a brilliant student to map his own "extreme running" - but which already has so much more depth in GPX handling than the MRA planner has today.)
