Hello @fititnt, 
About your request, I have no clue how to recover these POI.
My work on this project is validating, (in short) meaning, solving issues, correcting mappings. Squaring buildings etc. 
I never remove POI, or text added to buildings except when they are obvious nonsense, like generic names, hashtags of the mapper etc. 

I advise you to ask this on the specialized forum like
https://community.openstreetmap.org/
Or  Slack channel HOTOSM JOSM  

Best regards
