Coming to the Microsoft Intune Suite - Microsoft Cloud PKI!

This is an interesting feature but the pricing point becomes prohibitive for larger enterprises due to lack of tiered discounts, e.g.

1. 1000 users, $2 per user per month = $24,000 a year which isn't bad for the cost of a fully managed, resilient PKI SCEP infrastructure.
2. But 30,000 users at $2 per user per month = $720,000 a year - at that price point we could fund the cost of hardware, hosting and staff to support our own PKI infrastructure a few times over.

I know it can also be licensed within the wider Intune Suite but even with that the lack of tiered discount for larger volumes significantly exceeds the cost at which all the components become cheaper to do it / manage it ourselves.  

Are Microsoft intending to review their pricing structure at all to make for a more compelling large Enterprise offer for individual components or the entire suite?
