Just to confirm, these are optional right? We have default files:

default.fv
default.prop
default.meta

and the above override the per file versions above.

It would be great to have per directory defaults too that could override 
the defaults, but be overridden by the files above.

I'd go for *.meta.xml my reasoning is that we will also provide things 
like *.source.xml and other such patterns. With the locationmap it is 
not a problem that you are reserving extension, they can be changed on a 
per site basis if necessary.

Sorry, I'm not familiar enough with views terminology yet. Can you give 
me this in English, or even with a code example?

Good point.
