Description
When a command has persistent flags defined, these flags get inherited by all sub-commands and nested sub-commands. Let us consider an example.
root
- --subscription [persistent flag]
- get
- config
- subscription
- resource
- support
- update
The root command has a --subscription flag. This flag is marked as required using the MarkPersistentFlagRequired(). The sub-command get has a few nested sub-commands. I want to exclude the --subscription flag on the get subscription command.
Is this possible? If not, what is the idiomatic way of implementing something like this? I went about creating a persistent flag because most of the sub-commands require the subscription number.

Research direction
Start with Cobra's persistent-flag inheritance and MarkPersistentFlagRequired() behavior, using the root/get/get subscription command tree described here. Determine whether a persistent flag can be excluded from that nested command and identify the supported or idiomatic approach; the issue is done when this behavior and guidance are clearly documented.
