> Are SaaS businesses really customizing for high paying customers? They may build new features which are then made available to other businesses but I would be surprised if there are separate source trees. They are often using the same source tree and instance, but are enabling feature flags for certain customers. This often extends beyond code to data and caching. These don't get maintained and are a pain for support, as well as developers/operations. Over time they are almost as bad as a separate source tree.
