The WT consensus has been not to use stickers to highlight lines of ancestry or descent from notables except for a few generations before or after the notable - e.g., (1) the Mayflower Project has a sticker for descendants but it is only supposed to be used for descendants born prior to 1700 and (2) the US Presidents Project has a sticker for descendants but it is only supposed to be used for children and grandchildren of the President and a sticker for ancestors that is only supposed to be used for 4 generations before the President.
I think the reasons for limiting ancestor/descendant stickers in that fashion is that (1) WT profiles can have thousands or millions of connected descendants and ancestors, which means the potential for profiles to have a large number of stickers for lines of ancestry to and descent from notables, unless they are limited to just a few generations from the notable (note that WT policies limits a profile to having 5 stickers and 3 or fewer is better), (2) unlike paper genealogies, in WT, lines of descent and ancestry are not described or shown through designations on a person's profile but through the connections between the profiles and by using apps that allow you to see those connections - e.g., trees, Connection Finder, Relationship Finder, Ancestor Explorer, and (3) stickers are not automatically updated when connections are changed, so that a sticker designating a connection to a notable could easily become inaccurate without people managing the profile being aware of the change.
I also note that WT policy considers stickers to be optional cosmetic features, so that anyone who is a contributor to a profile can remove a sticker from a profile. As a result, there is no assurance that even an accurate ancestor/descendant sticker would remain on a profile.
