Databricks Unity Catalog Bug - Reset of Network Connectivity Configuration not possible

[mr_elastic]

The following use case is strange regarding the Network Connectivity Configuration (NCC):

1. I create a Workspace (the NCC is empty)
2. I create a NCC
3. I attach the NCC to the Workspace
4. I want to remove the NCC from the Workspace -> not possible

Therefore, I cannot go back to the state of a workspace with an empty NCC. This is very surprising.

This leads to the following strange use case:

1. I create a NCC
2. I attach the NCC to a Workspace
3. I want to delete the NCC -> not possible

The only way to delete an NCC is by creating a fake, empty NCC and attach that one to the workspaces. This is also very surprising.

We faced the very same issue in our Tenant.

This is the documented behavior in the REST API:
https://docs.databricks.com/api/account/workspaces/update
You cannot remove a network connectivity configuration from the workspace once attached, you can only switch to another one.
