This is a nice use case and surely will prove valuable to those who want to distribute their Glide applications via Amazon.
That being said:
Glide applications are meant to be custom software internal to businesses. When a business needs to distribute an app to their employees or partners, I’m not convinced it makes sense to send them to an app store or to Amazon. Instead, why not simply send them a link (URL or QR code)? As an analogy, if a business published an internal paper manual, instead of looking for a publishing house and distributing the manual in Barnes & Nobles, the business might as well print out the manual and put it on everyone’s desk directly.
