That means that it is a "braze-on" type of derailleur, even though it is not actually brazed on.
The tab is missing, I suppose one could be found or bought. Braze-on derailleurs of this type are very common now. There will be a limit on how low the derailleur can be adjusted. Could be a problem for smaller chainrings.
If new components are bought to upgrade this frame it will cost more than a completely new bike. And components compatible with the frame and with each other will likely be problematic (and educational).
