Hi Mike, It looks like there are indeed several projects that still seem to use isBlank() I used search to try to poke around and see what might still be using "isBlank()"
https://www.wikidata.org/w/index.php?search=%22isBlank%22&title=Special:Search&profile=advanced&fulltext=1&ns4=1 Like this one that I've just updated: https://www.wikidata.org/wiki/Wikidata:WikiProject_sum_of_all_paintings/Top_female_creators_by_number_of_collections Perhaps there could be a way to send notices to those projects?
