Sorry, no.  Please re-read rfc 2219.  Specifically:

     "These words are often capitalized."

The key word is "often" which means not always which means not required.

Computer science long ago made the mistake of imposing semantic difference on
case differences, which is distinct from other uses of case.  Absent explicit
specification of case sensitivity for the keywords, the rules of English writing
apply, I would think.

Not really.  Words like "can" and "ought" do the job nicely.
