views on views on views

I find myself constantly struggling with developers constructing views on top of views on top of still other views. I understand this makes their job easier in the short run but whenever problems arise that involve this kind of thing, my blood pressure goes way up trying to untangle the web. I've raised concerns in the past but that has gotten no traction and the practice continues.
I've raised the following concerns:
- Potentially cripples the optimizer
- When there is a problem with the set returned by the end-view, it is a nightmare trying to figure out where the problems is happening
- Makes it more likely that redundant filters are in place
There are probably more but those three are enough for me.
Do other people on the list have to contend with this issue?
Have you gotten the developers to agree to limiting their use of views in this way?
Have any of you successfully dealt with the issue and if so, what arguments did you make that allowed for that?
