Well, I did try PaSh on gnulib-tool — this issue [1] is a testimony.

But what can you expect from a parallelization approach? On, say, a
quad-core processor you can expect at most a 4x speedup. Which means,
the parallelized gnulib-tool.sh would still be 2 times to 25 times
slower than the Python rewrite.

Also, has PaSh been applied to configure scripts? I recall that
configure script parallelization had been a topic for Ralf Wildenhues
(before Google swallowed him).
