I agree, it's getting out of hand :)

Not sure what you mean by "rules", but generally I tend to use  
different config files for testing different things.
Much more convenient and less repetitive especially for the array  
options, like backends.

One convenient thing to note here: Using both a config file and giving  
options on the command line will cause the command line stuff to  
override the config file. Very helpful for increasing the log-level  
for example :)

I really don't want to allow people to use a programming language as a  
config option, mainly because I've seen some horrible stuff happen  
when they figure out they can write actual code in there :)
config should be for settings only, and application (== lua script)  
settings are already in the script, which sometimes is not pretty  
either.

What use case do you have in mind? Off-hand I can't see the need for  
scripting the proxy/chassis options, but maybe I'm overlooking  
something.

In the end, I think we need to come up with short names for the most  
often used options, although there is the danger of colliding short  
names from different plugins.
I'd like to think it would pick the first occurrence, but in fact I'm  
not sure what will happen.

I've included it here: https://blueprints.launchpad.net/mysql-proxy/+spec/chassis-short-option-names
