Hi Joe-w. Exeter and East Devon area has always been dominated by mapping addressees as nodes, usually within the building. Done primarily by areas three main mappers. Myself, Guy, and Wilpin. 

I personally didn’t bother with address for several years, and initially added them to buildings. When I started adding addresses in Topsham, it became obvious addressed buildings were nearly always wrong, or an assumption. From experience I found it was nearly always not possible to verify there was only one address is associated with a building. Then accepted the local style of adding address to nodes removed that issue."

The addresses added to buildings in our area are primarily from a user called sec147 in 2022.
His edits were questionable and appeared automated. He bulk added a large amount of addresses to polygons, often containing errors, and other issues.
His edits involved deleting address nodes, usually created by myself, Guy or Wilpin, and moving the data to polygons.

The link you give does not state or imply what I did was wrong? It also appears to be the creation of a single person? As is common in OSM, there is no clear rule

My edits were done to bring addressing into line with local mapping styles, with the next stage to find and fix errors created by sec147.

I see you've reverted my address edits. I wish you'd waited for me to respond first. You've done this by stating my edits are "undiscussed automated edits". My edits were not automated edits and clearly do not meet the common definition of that. I'll be a bit cheeky and state your reverts are undiscussed automated edits?
