I think a master password or PIN is very much like a "filing cabinet lock" and 
it does have value against curious people. Most people are not malicious and a 
simple lock sends the signal: "This isn't for you, and trying to bypass it 
makes you bad. I know you're not a bad person." It has value.

However, I imagine the line of reasoning for PIN or MP in the browser goes like 
this:
1) PIN or MP probably shouldn't be enabled by default
2) Most people don't change the defaults
3) Expected value of a MP or PIN is small vs the complexity of supporting it
4) There are alternatives for people who care, e.g., OS level profile locking 
5) Screw it
