Then if I have a need for a new tube or tire most shops aren't going to carry it and they would be hard to order. It all seems like downsides to me. If I wanted a bigger BMX bike I would go with a proper 24" which is a more common size but honestly I would probably stick with 20" like all the other BMX bikes.
All the adults I know who ride BMX ride 20" or I have seen people build up 26" and 29er stuff for cruising and such.
22" BMX is pretty common and tires and tubes are readily available. If not in stock at your LBS they can order them very easily. S&M, Fit, Subrosa, and Stolen just to name a few brads have 22" bikes or frames. The frames are closer to the geometry of a 20" than the companies can get with larger wheeled bikes.
