delete intermediary files = overcome local roadblock
make clean                = nuke the whole place

So if the whole place takes a long time to build up, why nuke it?

So, a user deletes some intermediary files, thereby potentially messes
up and consequently will have to nuke the whole place. I would probably
do just that to overcome any uncertainty; on the other hand, I would
prefer a system that does not require me to nuke the whole place if
rebuilding it takes more than a minute. But then, I'm not really a build
system expert so I might just be plain wrong.
