"True. In those situations where you want to switch your proxy 300 times per second, this is very important! ;)"
Well you never know... No, from a performance point of view you are quite right. However I have been in the situation where I've been on machines which are constantly running out of process ids and every little helps (eg: echo *). Admittedly I don't see switching your proxy on and off would be a particularly high priority in such a situation!
"Trading some performance for modularity and maintainability is usually a pretty good idea."
You've lost me slightly there, I would have thought having one .cshrc (or .bashrc?) would be more maintainable than a bin directory full of separate files. I guess we all have our preferred ways of working!

The PID overrun can also be thwarted by using "exec gconftool..." in the OP's scripts.
My maintainability concern with putting aliases in .bashrc is that only a single shell sees that.
Coming back to performance, the alias solution does incur the (small) per-shell cost of reading, parsing, and keeping in memory the alias, when in most shells you will never need it.
IIRC zsh has one-per-file functions that can reside in a directory somewhere. This is probably the optimal solution here: as maintainable as a shell script, loaded on demand, does not fork a new shell.
