That is not complety true with the current code. Other parts of the code depend
on this structure too (like the generic balancer code and several things in
proxy_util.c). So I don't think we should do that. OTH you are correct that new
balancers might need additional data. So it makes sense from my perspective to
add a void pointer *to* the proxy_worker_stat structure to enable
balancers to store custom data that is private to them. Of course we must take
care in this case that the same worker is not used by different balancers.
This would result in data corruption. In this case some sort of table would
be better where each balancer provider could use its name to get its data
pointer from the table.
