You still haven't looked at the thread you were pointed to, have you?
There is another issue besides disk space and performance, which is that
functions with large numbers of positional parameters are just plain bad
style --- it's way too easy to introduce bugs by passing the parameters
in the wrong order. It's usually better to coalesce some of the
parameters into arrays or records. Our awareness of this fact keeps us
from wanting to expend lots of work or resources on making the standard
function argument limit larger.
