This seems to be missing in NOTES.

This unimproves the commenting, since individual options should only be
commented on in 1 place (not here). This file shouldn't contain any
comments except meta-comments about what to put in it and technical
details. There are good examples of these at the start of the file.
More examples:
# Do not add comments on individual options in this file!
# Put comments on options in NOTES, not here!
# These rules should go without saying - see commit history

Should be more like +1 -4 to remove the comments, or larger to move the
options. Options that use a prefix so that it is obvious what subsystem
they are for are grouped naturally if they are sorted normally. Here is
an old patch that moves the MAC options and fixes a few of the other
style bugs in this file.
