This sounds like a great problem to have. I wish more developers thought about them sooner, to build the right kind of fundament rather than doing something that works reasonably well for the happy path but grows incredibly ugly when you try patching the inevitable edge cases. Perhaps it's not always needed to actually deal with those right away, but they surely need to be considered early on, so that it's fairly straightforward to do when the time is right.
