> I'd love to be able to separate myself and my team from others by an agreed-upon interface.

My experience suggests that speccing out such an interface well is a tremendous amount of work, and if you get it wrong (you most likely will) or if it needs to evolve it will generate lots of work since now it's set in stone and very hard to change so you're likely going to pay "interest" by working around its shortcomings for the foreseeable future.

I've seen the misguided adoption of microservices affect a couple of companies & products.

The interface will evolve, and in fact that is the hard part of software development.
