I don't think they would start allowing the use of professional jargon as spelling words, such as pneumonoultramicroscopicsilicovolcanoconiosis. But I may be mistaken.
That word would be of no challenge to the current top spellers. There was an 8-way tie for victory this year because the best kids are all but unstumpable. You are vastly underestimating the level of preparation that goes into competing to win the Bee.
For that and other obvious reasons, Scripps is unlikely to open the word list to include any and all nonsensical jargon.
What would you consider nonsensical jargon? Jargon is jargon because it makes sense to those in that particular profession (medicine in this instance) but not to those outside it. Jargon that doesn't make sense to those who are using it is just fiddle-faddle.
