Add an experimental or alpha flag for releasing bleeding edge features

[cdcabrera]

As a developer I need to consider implementing an experimental or alpha flag/option for releasing bleeding edge features without the need for semver major bumps.

Acceptance criteria

• implement an experimental OR alpha flag/option

Assumptions and questions

• would this activate additional flags/options?

• do we need to wrap features that may already have their own options for activation?
