Same as you, e-commerce store, along with other mostly web projects, quite a bit of real-time and long running requests. I also use Gevent extensively (I prefer it to asyncio). We use Gevent or Asyncio in a small number of routes that either have long running requests, SSE in our case, or have a very large number of rear facing io requests we can parallelise (a few back office screens and processes). The complexity that asyncio would add to the the code for the 95% of routs that don't need it would add a lot of unnecessary overhead to development. My point is, I don't believe it adds any value 95% of the time, but does, sometimes significantly, 5% of the time. I think it's better to only use it where it's really needed and stick to old fashioned, none concurrent, code everywhere else.
