For inactive games, there is an "on hold" tag that signifies that the Dev is still around, they just don't have time to work on the game. As for the "Abandoned" tag, I don't see it as an apocalyptic finality but as a "quick glance of the eye" way to see if a game has been updated while you're scrolling the site. Or a way to see if the developer has gone silent about it. As for the Dev saying "I'm done", there are so many other games on this site where their silence for months and years speaks volumes.
MLC may not be dead as disco, but by F95zone rules, the dev has been gone for 3 months.
