We used to use the #ArcGIS Parcel Fabric at work. There were all kinds of nifty tools for merging points, validating topology, etc etc. Ostensibly, these tools helped clean up the data.
Except… it didn't. Here's a parcel corner, zoomed in nice and close, with vertices symbolized.
As far as I can tell, all it did was hide things? The messed up corners and duplicitous vertices were all still there.
Now, though? Now we edit our parcels in #JOSM. 😎 (Not in #openStreetMap though, don't worry!)
