> Partial security is much better than none at all.
Only if you don't let down your guard because it's "secure". Again, there's a reason why they don't claim it's secure and everyone says to not treat containers as a sandbox.
The only people here who are letting their guard down are ones who're not even using a container/jail/VM for each project. JetBrains encourages this by not providing the container integration features for free.
