What is 1Password doing to simplify user access for companies using many vaults?

We follow role-based access, like many other companies would for providing the right and lowest amount of access to their users as their role requires.

In order to do this with 1Password for appropriate credential sharing, we have to setup many vaults per each of our customers, as well as our own environments/projects.

With us currently sitting at around 78 vaults, the UI, search and overall functionality is really starting to show a lack of scalability for the business.

• Sharing feature is not feasible due to expiration (nor would it be even if expiration wasn't there for the sheer point of manual process this requires)
• Duplicating passwords makes everything worse as credentials do not sync back to the original item.

My questions are, 

What is 1Password doing about this? Is it something you are currently aware is an issue and working towards a solution?

If you are aware, what is the priority? Do you have a timeline for any improvements?

As there is no solution, either other companies are in the same boat as me or simply setting up less vaults and accepting the security risk that people get access to credentials not required for their roles.
