FWIW the reason I don't use it isn't because I don't know it's available.
It's because when writing a test, it feels easier for me to just pound out
the dummy pass-through vertex shader rather than to go hunt around nearby
directories to find the shader I want.  I also find it slightly easier to
code review others' shader tests if they don't use this feature, because it
means I can completely understand the shader test in isolation, and I don't
feel compelled to double-check that the file they're referring to actually
exists (and does what it claims).

I like the idea of a "[vertex shader passthrough]" option--it would neatly
address both of the reasons why I don't currently use [vertex shader file].

However, I don't have terribly strong opinions about this stuff.  If you
want to just leave the series as is, that's fine by me as well.
