We aren't including it, we're giving people options.

Consider the case where the data comes from LDAP. How do you synchronize
changes in LDAP with the XML config file? A cron job? A manual "resync"
operation that must be invoked after each LDAP change?

There are certain types of configuration sources that simply do not map
well to "here is a config file."

I think what you should argue for is the capability to read config data
from a pipe. The other end of the pipe can grab the data from the source,
format it as XML, and shove it down the pipe.

IMO, we still want the modularization around the config stuff so that we
can read it from a file or read it from a pipe. Of course, that's just
reading from an fd, but there are more benefits to modularization.

Creating modules/abstractions within Apache is a Good Thing. Ryan's work
on constructing the internal tree (which has several uses) and
encapsulating the existing config reader has merit all on its own. If you
want to veto something, then at least wait until he starts dynamically
loading config modules :-)

Logging modules are a separate discussion. I generally agree with you
there, although I do think we could see some improvements in how we manage
the setup of the logging.
