Planner App just appeared for us in Sharepoint

Relating to my usecase should any of the Planner team come by the thread :

Release Planning

I currently use Planner to manage our Release Plans for updates and version upgrades we receive from vendors. While we have "plans" to integrate into a central tool, there is a period of easily the next 4-6 months where I want to continue using Planner for this.

I have a Release Sharepoint site that is basically the "hub" of all Release information, plans, projects and schedules. 

So I wouldn't want the messy overheard of tons of O365 groups and associated Sharepoints, when I just want the Planner use. Being able to embed multiple plans dashboards into a page, would be a huge win, for my userbase to see from a high level to see the status and schedules of Releases.

IT Team Based Agile Projects

Our Service Delivery team perform the large majority of projects within IT. We have a Team site in sharepoint we use for projects and collaboration, and again we would like to use Planner for each individual project as these are agile implementations and projects. We need lightweight planning, and we need to move fast for the business to get them in place. 

Being able to spin multiple planner plans of this single Team site would be ideal, again allowing transparency but also overview on the status of projects for the wider IT team, and our Dept Head, who might not necessarily be using Planner itself.

Currently the colleague who manages the "project plans" for these has one Planner Plan, with an almighty amount of buckets for each project and its basically a mess, and we lose the dashboard/reporting accuracy because of how it's dozens of lightweight projects bundled into one plan.
