I will go through the work listed there to understand what has already
been completed and what remains.

Thanks for the suggestion. I will start by studying usr.bin/talk.
I had initially started looking at usr.sbin/ypbind and currently have a
small patch prepared that replaces a gethostbyname() usage with
getaddrinfo(). Would it be better to send such patches to the mailing
list, or should I open a review elsewhere? I noticed reviews happen
on phabricator, I have gotten my account approved for the same.

Best regards
