There are IPR claims on the two IPPM drafts referred to in the handling of
this option.  I have not read any of the associated IPR patent filings
themselves (IANAL).

I read this situation to mean that the treatment of the data in the option
is likely to be covered by the IPR disclosures on the IPPM drafts
discussing their use.  Whatever is claimed about use of this information in
the IPv6 option is either competing with/related to the IPPM IPR filings,
or someone has attempted to file for IPR on "something/anything in an IPv6
option".

Regardless, as this document is just about putting the IPPM alt-mask
information into an IPv6 option I don't see that there's much in the way of
"alternatives" to be considered.  And "alternative" would be an entirely
different document about and entirely different option and (probably)
entirely different treatment of the information contained in that option.

But, IANAL
