I sort of work on platform engineering in the form of a test automation framework used by more than a hundred testers. In general it works fine but you have to be ready to scale up your platform team at the same speed or even higher than the users of the platform.
You also have to be very careful allowing the users to expand the platform to their needs or the platform team will be a permanent bottleneck. I have seen this in companies where the SAP people had a backlog of several years.
