I find multiple instances simple, ... divide and conquer. Each instance is
a single-purpose construction, with no tension between potentially conflicting
requirements. Perhaps unfamiliar at first, but not significantly complicated.
Then again, I instigated multi-instance support and wrote a non-trivial chunk
of the code, so not exactly a neutral reporter...

This is likely "not possible". Even if some gross hack could make this go,
by the time you have multiple config files, just go with multiple instances,
which are supported.
