I list the people in the household, usually in a === Census Records === section in the Biography.
In light of this discussion, I did not do so on an existing profile that had used narrative to provide census information from the 1870 census (see the profile for Thomas Gilley Watkins). I found it less than useful, but left it alone and did not add lists of the two additional Watkins households that I found on the same census page.
Since I thought that the heads of the three households (Thomas, Charles, and William) might be brothers, I went to the father's profile, which had not been developed, and added census info under Research Notes... and discovered that they couldn't have been brothers, if Thomas was the son, because William's household matched that of William Watkins, son of Henry N. Watkins, as shown by previous census records (1850 and 1860).
If I had not added the lists to the father's profile, or had not previously added lists to Henry N.'s profile, I would not have realized that.
So yes, I think that lists/tables are useful and helpful in the pursuit of genealogical connections.
And I think it would be unfortunate for a WikiTree project to have guidance forbidding their use.
