Well, per RFC2119:
SHOULD This word, or the adjective "RECOMMENDED", mean that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course.
Not following recommendation from RFC6177 by allocating a perfectly valid /64 (it being inconvenient to some is another story) is not "violates the documented standards"
