I rather like having the *concept* skin to talk about. While 
implementation-wise things may become cleaner, being able to talk about 
a skin is I think a bit more clear than if you talk about skin layers.

Similarly, I think it's a useful concept to talk to a layout developer 
about 'layers' as a separate concept, to indicate to them that a layer 
is not something necessarily directly exposed to an end user. I think 
that this use case is less strong than the one for maintaining the word 
'skin', though.

In various use cases, for instance Silva, there's a class of users that 
just wants to select from a list of skins installed for their site, and 
has no knowledge of how they're implemented. You don't want to show all 
layers to them.

It would therefore be nice to have a way to mark particular skin layers 
as actual skins you want to expose to end-users, not just as things 
useful as a building block. This is something we use the skin mechanism 
for now, and that facility would, if I understand it correctly, go away 
in this proposal.
