Mark exporters and generators as internal dependencies

[Hinton]

Type of change

- [ ] Bug fix
- [ ] New feature development
- [x] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

We accidentally exposed exporters and generators without feature flagging them. This PR properly puts them under the internal feature flag.
