Speaking of this, I sent the following to cyrus-devel in April, 2009. 
It's less complete than your suggestion and it wouldn't have helped in 
this particular situation.  I'm not sure if it's worthwhile or not.

Subject: Improvement to config file parsing code?

I discovered that the code in libconfig.c that parses imapd.conf really
has no way of warning you if you make a typo.  It looks like someone
tried to deal with this at some point, but that code is commented out
because it would die on any service-specific configuration options.

The patch I propose here relies on the fact that a service-specific
option must contain a '_' character in it, so this patch would at least
catch simple typos to real imapd configuration options.  Of course, this
patch is only valid if my assumption that all service-specific options
must contain an underscore is valid.

Thoughts?  If this would be useful, I'll throw it in bugzilla.  If it's
a dumb idea, I'll forget about it.
