@JeroenDeDauw regarding the license change, is it okay for us to switch the repo to MIT or Apache?

[JeroenDeDauw]

Let's do MIT, more concise and less legalese than Apache

[alistair3149]

For security policy, this repo does not have private vulnerability reporting enabled.
I don't have permission to enable that so perhaps @JeroenDeDauw you can look into that?

[JeroenDeDauw]

It's enabled now

[JeroenDeDauw]

I've enabled it and some extra security scanning stuff for all our (apparently) 43 public repos
