Voynichese is a numeric cipher?

[ololololo]

To me it's overwhelmingly clear that this cipher is too complex to read, which doesn't align well with my expectations about what style of a cipher it should be.

Well, it's relative. The most important thing about it is simply to solve the anagrams, which can be more time-consuming than deciphering the letters.
In my opinion, this cipher is simple in itself, because at the moment it's just a slightly more complex substitution. All you really need to do is decrypt the letters and get all the anagrams, and you'll have the plaintext.
It's worth considering making it a bit more challenging...

In any case, thank you for participating in this experiment.

And thank you very much!  The experiment proves that I'm not suitable for such experiments...
