Pekka - The specific text is ambiguous ... however, in John's message of 11/20, there is a sentence later in the same paragraph:
In this context, 'use DHCP' means trying to obtain only other configuration information through DHCP, not address(es).
That sentence clarifies the text I quoted.

I agree on this point.
However, the text you quote is ambiguous, which was the reason for my rewording proposal. If A node gets 'O' -bit advertisement (without M bit), and implements DHCP, should it try to run it in "stateless mode", without trying to get addresses or not?
That is, "use DHCP" is not clear because it can refer to getting addresses, other config information or both.
Similarly, "implement DHCP" is not clear, because you can implement full or stateless DHCP, which provide different functions.
This text needs a bit of revising.
