I guess that is partly because of changes in architectural tastes. Large staircases in grand houses are more as likely to be concrete or steel today. I suspect most woodworkers would never be asked to create something like that today, so perhaps there is no way to learn it?

Most compagnon masterworks are a show of skill rather than practicality. Staircases are typically chosen because they are a recognizable item and involve most of the techniques required to be a master craftsman.

Compagnons in other professions don't have the luxury of having everyday objects that work well as a show of skill. Plumbers masterworks, for example, usually look like an intricate mess of pipes with no purpose. It doesn't speak much unless you know the trade.

Another thing to realize is that compagnons are not any workers, they are masters. Maybe few people want grand wooden stairs today, but some people do, and compagnons are the ones who are getting the job.
