Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited integrations outside of web2py framework

   Documentation and examples are heavily focused on integration with web2py, making it harder to use in other frameworks or standalone applications.

2. 02

   Frequent breaking changes between versions

   v0.1 to v0.2 migration required rewriting chain definitions and adapting to new ORM features.

3. 03

   Small community, limited support
