Not just syntax errors, but interference between the different included files. These files would most likely be included in the main server configuration area of httpd.conf (and/or the SSL virtual host), they wouldn't necessarily be in their own virtual hosts, so it could tend to be problematic. I think you're right, it does allow us to do pretty much what we want, but there is more potential for problems than we'd like. Using htaccess files would be less problematic.
