Thank you for the feedback and waiting for this feature with patience. We have enabled download of a meeting attendance list during a meeting. This is released for general availability. Please note this feature is turned off by default, and needs to be enabled via admin policy.
See documentation for this feature here:
Note: We are continuing to work on enabling download after a meeting has concluded, as well. For status updates, check out the roadmap item https://www.microsoft.com/microsoft-365/roadmap?filters=Microsoft%20Teams&searchterms=66459.

This is really confusing for users today to have different experience, especially because we will move soon our 110 000 users organisation to Teams (In september 2019). If you can quickly add this feature it will help us a lot.
