You're explicitly asking about GTK+ 2.x, whose API was last updated 6
years ago, and whose initial release was in 2001.

GTK+ 2.x had a *very* simple theming API because all themes were
basically shared libraries injecting custom rendering into
applications.

GTK+ 3.x, at least, has CSS.

Of course, some people will moan that there isn't a function called
"gtk_widget_set_this_color()".

I don't know who these "kids" are, but if you mean "newcomers", I've
only seen people asking about changing colours of GTK widgets from
people sending emails to this mailing list, and a minority *at best*.
Usually, coming from software developers that are writing ad hoc
applications coming from other, or older, platforms, whose only
benefit is that they make it "easy" to change the colour of buttons in
UIs.

Sorry, we haven't yet found the way to write a `gtk_do_what_i_mean()` function.

Again, I have no idea what kind of "kids in GTK" you are referring to.
I see a lot of newcomers approaching GTK and GNOME development,
though.

You may be hanging around in the wrong places.

Ciao,
