Using new AzureRM provider functions in Terraform

There are two new pretty neat provider-defined functions with the new major release version of the Terraform AzureRM provider which I kind of missed initially but seem pretty cool to use.
normalise_resource_id
which tries to "normalise" the case-senitive segments of a resource ID in Azure.
parse_resource_id
which takes a resource ID and splits it into its different component parts.
Demo
I created some quick code just to try the features and wrote the following:

terraform {
required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = "4.4.0"
}
}
}
provider "azurerm" {
features {}
}
locals {
parsed_nsg = provider::azurerm::parse_resource_id("/subscriptions/(sub-ID)/resourceGroups/rg-prod-we-core/providers/Microsoft.Network/networkSecurityGroups/nsg-prod-we-core-dmz")
}
output "parsed_nsg" {
value = local.parsed_nsg
}
output "parsed_nsg_resource_type" {
value = local.parsed_nsg["resource_type"]
}
And the output in my terminal is the following:

parent_resources
is empty in this case as the NSG is not assigned any parent resources. A subnet would point to its virtual network.My initial feeling is that these two functions should be very useful to have since dealing with resource IDs in Azure is not always the most fun as they can be pretty lengthy.
What are some use cases you will find with these two new functions?
