I think this is contrary to the general opinion.

Possibly, but I fully agree with this. Of course, mine is also just an opinion...

I agree with the first paragraph - always have so doubt it’s a controversial opinion. 

 I’m only partly sold on the astronomical script. Alchemy borrowed much from astronomy/astrology and we’re moreover dealing, in my opinion, with a whole worldview mappamundae in the rosettes page and narratives in the balneoligical pages that incorporate a melange of different if rrelated ideas: astrological impact, Christian mysticism, myths of transmutation, alchemy, eschatology and prophecy, the water of life. Moreover, the huge section of plants plus the pharmaceutical section give more emphasis to an alchemical/pharmaceutical explanation than solely astronomical. 

Still, it makes sense that someone intent on devising a script would at least start with what they considered a celestial script- coming from the stars - and I have no quibble with that as a good theory. I think there’s an alchemical component though that makes it more complex. 

For fun, here’s my riddle: 

o+^=?
?+^=??
??\^=???
