add a null destination

Turns out this is in core already!

Although it does:

> requirements_met: FALSE

Doesn't that mean migrations won't run with this?

Doesn't that mean migrations won't run with this?

@joachim apparently not, as per discussion on #2857104 🐛 The "null" migration destination plugin can't be used Active .

Would it be possible to explain in the documentation how this plugin can be used?

Is it as follows in a migration yml?:

id: files
label: My files
destination:
  plugin: devel_null

@joachim : you still think this plugin is useful in this contrib module or can the Core plugin 🐛 The "null" migration destination plugin can't be used Active be used instead?

The core plugin needs some changes before it can be used, but let's see what the Migrate maintainers say on that issue.

And yes, like that:

destination:
  plugin: devel_null

Documentation should also say that nothing is saved to the map.

I close this for now. Feel free to re-open when it becomes relevant again
