I strongly agree with this! If you're working towards a product (and not just a hobby project) then these are crucial requirements. If they can be found out before writing any code, then they should be, since it will save time in the long run.

For me it's also the kind of thing that can lead to costly changes after the fact, which is prone to rub developers up the wrong way. It seems like the principle of phase containment might apply - if you found it early in the development cycle, then it would have been easier to fix.
