Agreed!
On my side, I worked in a different direction, starting from your

I noticed that the third chord goes from high to low instead of low to
high. That will mean your voices cross for that chord. Was that
intended? Also, it doesn't look like << { } \\ { } >> works very well
inside a tuplet (times). These kinds of things will have to be dealt with
by hand.

Looks good to me. I am new to this library too.

You could change relative to absolute in Frescobaldi before running the
Python script. Otherwise, it's not going to get the correct octaves.
