I would rephrase the first sentence as:

The Dynamic Host Configuration Working Group (DHC WG) has developed DHCP
for automated allocation, configuration and management of IP addresses,
IPv6 prefixes, IP protocol stack parameters and other parameters.

Saying that everything being configurable by DHCP is a TCP procotol
stack parameter is misleading. We also configure services and parameters
that have nothing to do with TCP/IP stack.
Also, referring to the stack as TCP/IP sounds very 80s. IP protocol
stack sounds better. There are documented cases of DHCP users who used UDP.

I would reword this item slightly:
Develop documents that are related to operational considerations of DHCP
for the wider community if and as needed.

There are two changes here. First, "explain" is removed as we may do
more than just explain. We could recommend some practices or discourage
people from doing certain things. Also, defining configuration
mechanisms, such as YANG models, is part of the operational
considerations. Second, without DHCP added, some may take it out of
context and say that DHC can make any operational consideration
regarding things other than DHCP. This is particularly likely with the
"wider community".

During Singapore meeting we had a discussion about defining IOT options.
The general suggestion was that some external organization (IIRC OASIS
was mentioned) is better suited for such work. This approach would be
similar to what DOCSIS did for cable modems. Do we want to explicitly
mention "external organizations" in here?

The remaining text looks good to me.
