I think there's a slight difference between doing something that nobody's ever done before and just choosing a less travelled path. In any case, I'd rather not use the tool with well-known foot-guns, hoping that all developers in the project (and future ones!) do know these foot-guns as well.

I'd rather chose a tool with less foot-guns (or if not possible: provide easy workarounds that are consistenly used). With the design-flaws of express (no fault to it, since it predates standardised Promises by more than 5 years) and the availability of a simple and sane evolution of its API (koa), I really don't get why so many still cling to express.
