The requirement for Google Classroom is really disappointing. I understand what you are suggesting about enabling it and just not using it. But, that really isn’t a solution for us.
At our school, we can not have a second LMS enabled for our teachers, students, and parents that cannot be audited by the academic administration. Google Classroom is nice, but it is missing all of the SIS integration and reporting we need. Enabling Classroom will add it to the Google Apps Launcher. That would make it really easy for teachers to discover and start “accidentally” using.
There are other 3rd party edu Google apps we have installed from the marketplace that work well without the need for Google Classroom. Brainpop, Lucidpress and Lucidchart come to mind. They were able to verify we are an educational organization.
If you could somehow change how the verification of edu accounts works, that would help us out greatly.
