I think will be good idea to create dedicated log for properties creation. Property type should be reflected there too. Special:RecentChanges for Properties namespace is hard to use because properties creations are flooded with their translations. Alternatively properties translation could be marked as minor edits.
https://www.wikidata.org/w/index.php?title=Special%3ANewPages&namespace=120&tagfilter=&username= can be useful?
Almost what I thought of :-) Only type is missing. Sorry, never used Special:NewPages in my practice :-(
