Enable Persistent User Preferences Without Custom Connectors

It would be valuable to have a frontend-supported way to store persistent per-user data in Gainsight CC.
My suggestion is to extend the new Web SDK with the ability to set specific user profile fields from the frontend, without needing custom connectors.
Ideally, this could use a new hidden user profile field type, perhaps called API, which could be included in the JavaScript inSidedData object and updated through the SDK.
Example use cases:

• Permanently dismissing an onboarding widget per user
• Storing frontend-driven customizations, such as product-specific subscriptions or preferences
