Plenty of people are not interested in having a stamp under their alias, irrespective of whether its Artifex or Citizen. They are here to make and/or use mods and engage with like-minded people. They don't seek recognition from the community or involvement in the politics of the site. This is why there are some well-known modders and contributors without titles.
As it so happens, I rejected a variety of patronage offers prior to my eventual acceptance - despite knowing that I could have chosen between "Artifex" and "Citizen". The only realistic reform I can imagine that would make folks more likely to accept the Artifex/Citizen designation would be the removal of the requirement that potential candidates write what amounts to a cover letter. Let the patrons do that.
