Is anyone worried about Microschools becoming too big?

I’ve seen a few reports about how Microschooling is becoming more and more popular as time goes on. I’m worried that we might lose the “micro” part of them and wind up with too many students and not enough teachers like a lot of public schools. Can these places be built and accredited fast enough to keep up with demand? Or are the parents going to have to do all the work themselves?
