One could just as easily get a few cheap laptops from a rummage sale and install Linux on them and turn them into powerful APs within a few minutes with a live environment.
While I agree that you can, and I have done so before (at home). There's frankly no way I would ever even consider something like this in a business environment. Depending on your work situation, i.e. full or most time work from home, this would include my home.
I would especially do this in a work situation. At least with a Linux install I don't have to worry about all these typical routers and switches with their built-in hardcoded vulnerabilities threatening my work network security.
