> Teams typically implement their earliest version of an access control system with a home-grown solution or an open source library. Many implement role-based access control, often with roles, attributes, and authorization logic hard coded and/or tightly coupled with their business logic.

Here's the thing, teams do this for a reason. Each one of these checks takes all of 2 minutes to add. And the next one takes 2 mins to add, and so forth. Until it's a total mess. But, as someone who been through this cycle multiple times, that's exactly what I would do again in the future. Because, on day zero, if my options are "the 2 minute solution" or "spend hours/days/weeks? evaluating a vendor for a problem I won't have for years"... well, the choice seems pretty clear there.

> As a product grows in usage and complexity, this is no longer enough. But the thing is... while it's not enough... I can add to it. Far more easily than I can to refactor everything to support a vendor provided system. And I know it'll be a big ball of mud, but at just about every decision point along the way I'm better off not switching. And every time I add something to my system, it's that much harder to adopt yours.

It feels like there's a circular dependency here. The easiest time to adopt your product (day zero) is also when I'm least likely to get value out of it. Solve that for me, and I'm very interested in your product.
