Hey @bradrees! Thank you for PR but I think proposed options in #117 are good enough to make it work for seeds.

I'm not sure I agree - creating a new environment is quite a big change, and breaks things like Rails.env.development?, which I know is an anti-pattern, but it still useful in a dev environment. It also doesn't allow us to disable and re-enable within the same process.

I do feel that having the basic option of a simple on/off switch is beneficial in a number of ways, and I'm clearly not the only one, as there are already outstanding issues and forks from others.

It's not like the PR is complex either, it's a boolean accessor and an if statement.
