Yes, we should have a way back from SoM as well as ToTW. There is already a short-cut added for getting to Smuggler's Den .. I don't recall if it includes a return route ... it and CoH are a higher level dungeons anyway. Foreman's has a whompa nearby and a beacon you can obtain with the quest ...
The point of many of these posts is very similar ... for new players and smaller toons there should be a way back from these lower level dungeons when toons are of a size that yalms are too expensive.
Re-use the ToTW letter on an item to return to Rome or Newland Desert ...
Click on the Eye outside SoM to return to Newland City ...
Or, make the jetpack free and available all the time or available as a questable item that small toons (lower than 25) can successfully complete.
Or something similar.
