I do work on this code, so I have some idea of the maintenance burden.
:) But as I said to Zach, you still have the maintenance burden if
you defer this level of detail to view specs.

I am actually not a big fan of "flexibility." It's great if it's free,
but I don't find it persuasive in and of itself. I think this aligns
with the original principles of XP. I have had projects where a new
interface was required at some point. But the vast majority have not.

I was really describing the way I approach scenarios, not prescribing
anything for others. I really hate writing view and controller specs,
and I've found (so far, at least), that describing user interaction in
scenarios obviates them and is better for communication with users.
Other people's mileage may certainly vary.
