Those daemons certainly have very little in terms of private data memory usage, so all of them will share the same memory pages in practice. And it is certainly best to have only one location to deal with syslog usage than having each server programs to do it, after figuring out if they are actually invoked in a context that requires syslog instead of stderr. Having the git daemon deal with syslog, and log any abnormal exit code from the programs it spawn is IMHO a pretty logical thing to do.
