Hello,
I just want to inform you (in case you don't know it already) that those "descriptions" are so called Gewannnamen (historical names) and are still visible in ALKIS (but mostly not OTG). Sometimes those names looking weird ("Zwischen den Wegen X and Y") and there were discussions in the past if we need them in OSM (I personally don't) and which tag should be used. As far as I know that discussion ends with no real concensus (as often :-)).
Deleting them could be short-lived, because as I mentioned they are visible in ALKIS and another mapper could recreate them.
Regards
