I'm using themes in my zen-mode.el package. I use it to create a
stackable set of features. Maybe it's easier with an example:

0:
1: A
2: A B
3: A B C

so; A B C are features. 0 1 2 3 are levels that you can switch between.

Customize makes this feature a bit problematic, as you have observed. It
happens frequently that a variable I want the theme to own winds up in
the default customize level instead. Then my entire stack fails, since
it means feature C winds up in level 0. I haven't delved much further. I
reported a bug at least.
