Seems extremely unlikely there's a "high cost" because it's already clear there's some strange properties involved in LK99. Cracking the explanation for this could potentially help advance material science in all sorts of ways. In some ways this is pure science. Multiple groups working on the same thing increases the chance of searching the problem space thoroughly, and not missing out on finding better local maximas.
