All the components that are worth using have hooks into the greater Airtable ecosystem. If they made them available outside the Airtable Custom Apps platform, it would likely affect their business model by allowing too much access into the ecosystem from the outside.
Also, many of the useful components seem to check the status/type of the logged-in user to determine if edits can be made. That check wouldn’t be able to be made outside a logged-in user in the Airtable ecosystem.
So for those reasons, I’m going to suggest that it seems highly unlikely this will ever happen.
