I don't think so. It's fine to simplify things if you know what you're
doing. I would, however, suggest only simplifying files that need
local changes. That will greatly ease updates and reduce the number of
dpkg-conffile questions asked during updates.

dc_smarthost is the writing in update-exim4.conf.conf, which gets
translated to the exim macro DCsmarthost by update-exim4.conf. So if
you directly define the macro inside exim configuration, you need to
use DCsmarthost.

Unfortunately, exim -bV does not check for such errors, so we cannot
flag them at daemon start or configuration build time.
