I had (and still have) _no_ idea.
I think Gnome people have this very strange dichotomy:
- "We have tons of config options.." (it's true, sometimes, just not
where I cared)
- "..but we hide them, because only experts should use them"
and then they think that just because you're an expert in one thing, it
means that you should know *Gnome* intimately.
In past discussions, I've seen people think that since I'm a "developer",
I should use a text-editor to edit binary configuration files by hand (and
anybody who calls XML "text" has drunk a bit too much of the cool-aid).
I don't understand that. I'm a *kernel* developer. I may do *kernel*
configuration by editing text-files (and they are _real_ text files),
because I find that to be more efficient, and I know the options better
than most.
But do I think that Gnome developers should do that? Hell no. It's why
we've merged various graphical configuration utilities that have
help-buttons etc (and don't get me wrong: I don't think those are perfect
either, and we had a small flame-war about how to make it easier for
people to see dependencies between different choices just in the last
month).
This is why you want graphical tools (that are there by default, so that
you don't have to know enough even to know to get them) to configure stuff
even for "experts". Because I'm an expert Unix user, but that doesn't mean
that I'm expert in some Gnome internal configuration issues. I know what I
want, but that doesn't mean that I know how Gnome does it.
This is also why I actually made the patches to "gnome-control-center" to
expose the things I wanted in the window control panel. Not because I
personally *needed* it any more (now that I wrote the code, I know which
magic command line to use to enable it), but because I know that even I
will forget - I tend to install new machines maybe twice a year, which is
the only time I really want to configure my window manager, and that's
simply not often enough for me to have to "remember" things.
And yeah, the control-center patches actually ended up being larger than
the metacity patches (the biggest part was the Glade XML thing, btw: there
really is something seriously *wrong* with XML, but that's a whole other
discussion in itself). But _I_ believe that to make a configuration option
really "exist", you have to expose it. Not hide it away for "experts".
Linus' law (nr 76 of 271):
"Don't claim to have a config option, if you don't actually have the UI
to change it"
Because it really does boil down to the same "users are different, and do
things we don't expect". Replace "users" with "experts", and it will still
be true - perhaps even more so. Nobody is an expert on the thing _you_ are
an expert on.

Quite frankly, I gave my daughter as an example just of the kind of "yeah,
you can certainly do confusing things even with gnome". I don't feel like
I need to control her in this area - confusion and experimentation is how
people learn. I just realize that others may not be as happy having the
people they support experiment and screw things up.
So I don't personally think that "parental controls" are necessarily the
thing to look for, but yes, I think that kind of technology can also be
used for "limit confusion by limiting choice". Some people are just better
off not being confused.
