Great! Will CTAN ever see this piece of code? Since I do not completely
understand what's going on here I'd like to ask some additional
questions regarding the code.

Is it true that there would be no need to save '=' (for the final for
loop) if one chose another assignment character in keyval syntax, e.g.,
a colon? (Since this perfectly works there's no need for changing that.)

An arbitrary return value (zero or -1) would work here as well?

What is the difference in '=' before and after these changes? As I
understand it '=' refers to _assign which in turn refers to _equals
which is the same as '='.
