/etc can be ro (for the most-part), but of course /var has to be
read/write.
Remember that /etc has to be kept in step with /usr - for example, if you
upgrade sendmail to 8.10, then everyone has to reconfigure it at the same
time. Even if sendmail 8.10 works with 8.9 config files (they do look
pretty similar) you can be sure some things will not.
If you control it on one machine, then you can cut individuals over to the
updated /usr as you get their /etc fixed up. Assuming you have a
mistake-proof way of doing it;-)
