Ted, the allocation policy for the Private Enterprise Number (PEN) code for users
of DUID-EN is not Standards Track; anyone and their brother can easily obtain a
PEN code by filling out a simple form:

https://pen.iana.org/pen/PenApplication.page

I did one for “LinkUp Networks”, but that is not in any way tied to a Standards
Track RFC. IANA did not even ask me any questions; they simply allocated the
code for free. So, as far as standards status goes, an arbitrary PEN code has no
standing while the global IPv6 unicast address space has full Internet standards
status according to RFCs 4291 and 8200. I would therefore see it as a major
DOWNREF to entrust the entire IPv6 address space to any random person
who decided to register a PEN code.

That, plus I don’t want to carry around the extra 4 bytes for a PEN code…

You said this before. I don’t understand what this means. DUID-EN is in a standards track RFC. How is this a DOWNREF? And why use an arbitrary enterprise number?
