ok, let's give it a shot then.
And watch for behaviour changes...

The getopt language is imprecise, and attempts to be precise with it
usually go poorly.
For example,
SYNOPSIS
ls [-1AaCcdFfgHhikLlmnopqRrSsTtux] [file ...]
% ls -1AaCcdFfgHhikLlmnopqRrSsTtux
The result may seem surprising. I claim the result is not surprising.
It is unsurprising because
-c Allow new files to be created; otherwise uploaded files must
already exist. Files are created with default permissions
allowing anyone to read or write to them.
Works for me in diskless(8) usage and manual tftp(1) get/put testing
with existing and new
Scripting tftp(1) makes it non-interactive, yet the prompt is still
printed and may mess up the shell's PS1:
$ echo put nonexistent | tftp localhost
tftp> tftp: open: nonexistent: No such file or directory
tftp> $
The fix seems easy and works as expected for multiple
rarpd(8) either "Listen[s] on all the Ethernets attached to the system"
or requires an explicit list, not both:
$ rarpd -a em0
usage: rarpd [-adflt] if0 [... ifN]
$ ./obj/rarpd -a em0
usage: rarpd [-dflt] -a | if ...
Or would this be better?
rarpd [-dflt]
dhcpd(8) has

Feedback? OK?

diskless(8) just needs tftpd(8) to deliver files, none of the possibly
untrusted clients are supposed to ever write anything.
Either way, even when run without -c, a single file writable by _tftpd
might be enough for a malicious client to fill up the server's disk.
A proper read-only mode
Searching for a command in help output is much simpler when sorted.
The strings can be inlined into the struct while staying under 80 chars.
Now manual and help output are in the same order, except help folded
into ? in the manual to avoid duplicate text there.
Or should help appear at the same

And I continue to disagree.
Another example of the same pattern is ifconfig. Here you will see it
is not documented that [-a] is
