I think your tutorial would have more impact if you had a super short intro making a quick mod using the web page. The existing stuff is excellent for those who get a surge of dopamine from updating the map and want more power and control. The web editor is far from ideal but the app has a greater learning curve. Even installing it can be onerous.

I used the web editor recently to add a street and path and to fix some names. It was about as clunky as the Google Maps web editor which I used for the same updates.
