you discount the overhead.   The current major problem with 2.2 as far as I 
understand it is that it is very slow in building docs, because the start-up 
overhead happens for every snippet.  I think the biggest risk for this is a 
bigger likelihood for developers to skip the make doc step, which used to be 
the gold standard for committing.
    
    To the contrary, now that Guile 2 byte-compilation
    has been fixed I see *faster* startup time with
    Guile 2. To wit:
    
    
    - Official 2.23.4 binary with Guile 1:
    
    $ time echo "" | ~/lilypond2.23.4/bin/lilypond -s -
    
    real    0m0,445s
    user    0m0,401s
    sys    0m0,047s
    
    - Self-compiled LilyPond with Guile 2:
    $ time echo "" | out/bin/lilypond -s -
    
    real    0m0,247s
    user    0m0,233s
    sys    0m0,019s
    

That is great news!
