Acting Libraian

Should David Mao be removed from this template. Most other lists don't include acting personal- see for instance https://en.wikipedia.org/wiki/Template:United_States_Secretaries_of_State . Furthermore there are gaps between every other Librarian of Congress, but no acting personal is listed for them. I am unable to find a Wikipedia standard for this, but I don't believe acting personal should be included. — Preceding unsigned comment added by 148.167.132.249 (talk) 19:27, 2 February 2021 (UTC)[reply]
