Any kind of Service Provider thing over Nostr is a waste of kinds that can be reserved for better stuff.

At least, when providing such ideas, use one kind and make them different with a tag to show the type of request.
Not just reserve another kind that probably only you need until the end of world.

If you want to make a new HTTP API, you don't update the HTTP RFC spec, you define your own routes and stuff by changing parameters that you have access.

So if you have a new service over Nostr (Using a DVM or anything similar) just use the same kind with a different tag, maybe called the type or function.
