In the current version of Contexture it is possible to nest Domain/Sub-Domains without any restriction. But for a lot of systems it's enough to have domains and sub-domains as the only way to structure their bounded contexts.
To reduce complexity for the users either
- limit the nesting depth to domains/sub-domains
- introduce a configuration to limit nesting depth to a certain level (e.g. 2 levels - domains/sub-domain/sub-domain)
Option 1) will be easier to implement, document and maintain. But it could limit the usefulness of Contexture for some users.
