Hi, I've found some more support for doing exactly this:
https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2

"
Any LWS that occurs between field-content MAY be replaced with a single SP
before interpreting the field value or forwarding the message downstream.
"

As far as I know LWS includes the newline-whitespace sequence.

It seems to me quite clear that any compliant interpreter of header values
should be insensitive to the switch from any amount of linear white space
ce to a single space within the header value.
