Currently we have an efficient and simple set of rules regarding properties.

We simply match two sets of properties to find out whether A is a subset of B.

However, that is not correct because we must treat cuda::mr::host_accessible differently because it is the implicit default, so resource_ref<> is equivalent to resource_ref<cuda::mr::host_accessible>

This requires us to do some complex determination whether we need to actually extent the passed in set of types

Currently we have an efficient and simple set of rules regarding properties.

We simply match two sets of properties to find out whether A is a subset of B.

However, that is not correct because we must treat `cuda::mr::host_accessible` differently because it is the implicit default, so `resource_ref<>` is equivalent to `resource_ref<cuda::mr::host_accessible>`

This requires us to do some complex determination whether we need to actually extent the passed in set of types

resource_ref<> is equivalent to resource_refcuda::mr::host_accessible

This is news to me. Why is this the case?

otherwise we force the user to always pass in a property

Is that bad?

It is not bad, but it is a choice.

Effectively that means, that resource_ref<> is not a valid type and we would have to add some checks that a user provides either cuda::mr::host_accessible or cuda::mr::device_accessible or both.

That could lead to issues moving forward when the user provides their own properties that do not exactly match ours.

Furthermore, it will remove a bit of convenience. A user cannot write cudax::vector<int> but would always have to write cudax::vector<int, cuda::mr::host_accessible>. That should be easy to away with aliases but it is an incconvenience

After internal discussion we decided that it is best to always require the user to provide an execution space property.

All this implicit behavior is surpising at best and harmful in the other cases
