I watch the project and did not see "UNMAINTAINED", cause i scroll automatically on github projects down to the readme.

I search and then i see it in the title.

Better would be an Option in Github to set a project to unmaintained or deprecated, with an optional link to the new project (if some exist).

Github could then change the background color from white to an other color or add a border around the page, so that it is really obvious that this project es EOL.
