Doesn't read smoothly .... and infact turns into a directive rather than a 
permission.

One alternate to illustrate my point ...
    "SHOULD be removed" --> "SHOULD be able to"
another ... replace the remainder after "the field value is ignored and"
with:
     "removing OWS before or after the field value SHOULD NOT change the
      meaning of the header field."
