CLINK might already obviate the need to send a Lightning.Pub invite directly from ShockWallet

If you run a Pub and are using CLINK with SN, SN already has your Pub's nprofile.

SN also already tracks signup referrals.

The new CLINK enroll method could be used in SN to automatically provision a new users wallet on the referring users Pub automagically.

Use Pub on SN -> Refer users to SN -> New SN user is a Pub guests of yours.
