Is there a need for a book for Adobe Stager similar to the "Adobe Classroom in A Book" series?

I'd come back here and ask this question in 2 years. Adobe Stager has just been born, and is evolving at a rapid rate, - any printed documentation is very quickly out of date.  Back in time, I spend so much money on books, I loved knowledge I could get out of a great book.  Today, I wouldn't spend money on any book that relates to a specific piece of softweare, because all softwware is constantly evolving. Sure, a book about Photoshop will be longer lasting, because so many of its features are locked in,  -- the same can't be said for Stager.  If you go to Adobe's channel and look at their first tutorials for Stager, you can see the program has evolved and changed so much, many of these tutorials now can make you feel lost because things have been changed, and moved around ( GUI ) etc.... that's just my opinion.  Later down the line ( a few years from now, hopefully Stager will be established where printed matter may still work for some people )  There are many people who have gone this route thinking they would make big $, and barely recuperated print costs, or have fallen very short and have a garage with 100s of unsold books ( I know somebody like this )  It's a risky business move in this era if I'm honest.  99% of people go to YouTube and forums for immediate help on a daily basis.  Would love to hear other's thoughts on this, it's an interesting topic.
