(replace-regexp-in-string (rx (one-or-more (any whitespace))) " "
"Hello    there

and    here") ⇒ "Hello there

and here"

new line is not removed with character class `whitespace'.

(replace-regexp-in-string (rx (one-or-more (or "\n" (any whitespace)))) " "
"Hello    there

and    here") ⇒ "Hello there and here"

So now it will work that way.
