What naming convention should be used for tags about Arkham Horror and Eldritch Horror expansions?

Question

As the Arkham Horror tag wiki and Eldritch Horror tag wiki shows, there are two naming conventions that are currently being used for expansion tags*:

Early Arkham Horror expansions do not have a prefix

• Curse of the Dark Pharaoh curse-of-the-dark-pharaoh
  • Note that ah-curse-of-the-dark-pharaoh is longer than the allowed 25 characters
• Dunwich Horror dunwich-horror
• Kingsport Horror kingsport-horror

Later Arkham Horror expansions have an "ah-" prefix

• The King in Yellow ah-king-in-yellow
• Innsmouth Horror ah-innsmouth-horror
• Miskatonic Horror ah-miskatonic-horror

Eldritch Horror expansions do not have a prefix

• Mountains of Madness mountains-of-madness
• Forsaken Lore forsaken-lore
• Under the Pyramids under-the-pyramids
• Strange Remnants strange-remnants

What should be the naming convention of these Arkham Horror expansions going forward? And when we reach a consensus, could a mod or high-rep user please migrate tag wikis?

Answer 1

They probably should have the ah- prefix, since as far as I can tell all other games that are an expansion for (or related to) another game have the games name (or abbreviation) as a prefix. Examples: dominion-seaside, catan-seafarers, and mtg-commander

I didn't find any other games that don't fit this pattern (but it is possible I missed something from a game I don't know much about)
