Shipping ten times as much is not an advantage, because the moment you ship something you are stuck supporting it forever and every later feature has to interact with it.

The moment you ship something, you're stuck supporting it forever. And by supporting, it means any future feature you build is going to like interact with it. So you still have to be very conservative with what you put out there. It's hard to undo anything. Just cuz we can ship 10 times more doesn't mean we have 10 times as many good ideas to ship out there.
