It is mandatory on _network level_, not on api level.
F.e. checksum is mandatory for ICMPv4 too, however, we used to calculate it
in user space and nobody cries about this.

Do you see what is the mistake in the rfc? Authors did a wrong sillogism
and had to write several paragraphs of meaningless text to explain the mess.

Shortly, you may consider this as a compatible extension of standard API.
(which costs deleting several lines of code. :-))
