Yes, absolutely, it makes sense to have WAC added as an award that one can apply for via LoTW. In fact, it and a few other awards are on the to-do list. Also on the horizon is a refresh for LoTW, up to a 2.0 level.
Both are very much in active review on this end. More updates will follow as we have news to report on either.
+ Bart, can you comment on the status of hiring the developer(s) necessary to implement additional award support in LoTW?
