And maybe you can.  I like the idea of a microservice architecture, however:

   - You may want to inspect the database without shutting down your
   application process.

   (It occurs to me that an in-process ZEO server might be an interesting
   future feature to address this sort of situation.)

   - If you have high-availability requirements, then a single process with
   a single local file won't work in the long run.
   - That's probably not an issue at this point.

That would mean all data management tools would have to go through that

You could wait until you feel the need. Perhaps during development, it's
not a big deal to stop your app development to look at the database.

I'll elaborate in a separate message.
