The sentence
" Among these types of addresses only the IPv6 link-local addresses
MAY be formed using an EUI-64 identifier. "
is the logical equivalent to
"non LL Addresses MAY NOT be formed using an EUI-64 identifier". This should be said in a section that discusses non LL Addresses.
That 'MAY NOT' is your understanding. For me the 'MAY NOT' is absent,
silent. I can not put a 'NOT' on something that is widely deployed
today (MAC-based IPv6 GUAs are in widespread use, especially in the
embedded world).
In the section we discuss non LL addresses (section 4.4 "Stateless
autoconf") we RECOMMEND stable IIDs (RFC8064) and MAY semantically
opaque IIDs (RFC 7217).
In that section 4.4 we also say MAY use RFC 2464-based IIDs (MAC-based),
during transition time. By transition I understand towards a better
later world when embedded linuces moved to kernels 4.x (currently at 2.x).
Is this approach not ok?

All the best,

This text should not be in a LL specific section since it deals with
the other addresses. Maybe rename the section to "addressing" or
something?
The titles of these sections come directly from the RFC2464 IPv6-over-
Ethernet.
The title of this section is 'Link-Local Addresses' and as such it has the Address
root in it.
The text deals indeed with other kinds of addresses, in that it says 'There are
several types of IPv6 addresses'. But then it gets specific to LL addresses. The
'MAY' keyword is only applied to LL addresses.
As such, I do not understand why do you think it deals with the other kinds of
addresses (non LL)?
