Does it still make sense to use Swap with Btrfs?

The reference configuration is Manjaro Linux default for this particular usecase.

There is a topic discussing which HOOKS would be correct and what syntax should be used

And comment referencing what choices can be made and why one would choose to do so.

I don’t think it applies for this discussion - which is using the default Calamares to install btrfs with encryption and swap.
