Happy to see very old unmaintained feature be removed.

Hello,

I was researching Knowledge Base Security report Management for a University seminar.
And found this project.
I was interested in how helpful a rule base System can be.
Do I interpret this PR correctly that the Rule Framework is removed?
It is still prominently promoted on the Project website?

Thanks,
Marc

A rules based system would be incredibly helpful! However, the one that was implemented here was incredibly dangerous. There were practically no guard rails around the capabilities of the rules framework. It was initially hidden with deprecation methods, and then recently removed for users protection.

@marcnnn +1 to what Cody said.

The rules framework, while powerful, allowed direct access to DefectDojo's internal objects and, if you weren't very knowledgeable about DefectDojo's internals, it was quite easy to corrupt your database into an unusable state.

I honestly forgot it was listed on that website and we can remove the reference from the website. we missed that when we removed the code portion of the rules framework.
