contrary to your advice, I took the initiative and coded <IfThreaded> against 2.1. basically, this would allow you to group threaded directives together. so, instead of this
<IfModule worker.c> ThreadsPerChild 5 </IfModule>
and so on for every threaded mpm, we could have
<IfThreaded> MaxThreadsPerChild 5 </IfThreaded>
This rubs me the wrong way FWIW. I think it is best to have all directives for a specific MPM together in one container, and have that container specific to the MPM. If somebody really wants to do this they could use IfDefine; though it would be easier if the core pre-defined some symbol for use in IfDefine, it is doable as-is.
