The honest limit, said here and not on a call
Two different problems
Once the history question is out of the way, it is worth separating what is actually being compared. Scheduling and workspace are two different problems, and Planner Premium only answers one of them.
Planner Premium answers what tasks exist, in what order, and by when. It does not answer where the project's documents live, who has access to them, what the risks are, who the stakeholders are, or what was decided along the way and why. Those are workspace questions, not scheduling questions, and a scheduling tool getting better at scheduling does not make them go away.
Why that will not change on its own
What a project workspace looks like instead
A SharePoint project workspace is a different kind of thing entirely: a site for each client, with a folder and Teams channel for each project, a document library, content types and site columns already set up for the work, its own navigation, and default folders already in place. Each project has its own Planner board, seeded with starting tasks, and each project links back to a central project registry so the record of what projects exist stays accurate instead of becoming a list nobody trusts.
This does not replace the Planner entitlement already included with most Microsoft 365 licences. It rides on it. The board is still a Planner board, opened the way your team already opens one. What changes is everything around it: the site the board lives inside, the documents that sit next to it, and the record that ties the two together.
None of this reaches back into Project Online. It is not a migration, and it does not claim to be one. It is where your next project lives, built correctly from the start, inside the Microsoft 365 you already have.
