  How do you preseve them?  As the encoded "%2F"?  Do you convert the
encoded values to uppercase?  Lowercase?  Keep them the same?

  But you said it yourself, you fall on the pragmatic side.

  Well, I do have one [1], although I'm not sure how "full-fledged" it is. 
I also lowercase the actual MIME type (so "TEXT/PLAIN" will become
"text/plain") to make it easier to use the results.

  I even have one for email [2], which can even parse RFC-822 style email
addresses [3], but I'm rethinking how I parse Internet messages as I'm not
entirely happy with my current approach.

  Life is too short to follow the WhatWG "standard" [4], so I guess it's a
"pick your poison" type situtation.

  Yeah, let's roll our own crypto and addressing scheme!  What can possibly
go wrong?
