But are you going to initiate a scan from a low-end feature phone? Would you want to?
*If* that class of device is really important to support (which I question), then we should make push scan unconditionally required. However, if we decide to set the bar high enough that the client is capable of viewing web pages and images, sending emails, etc., then I don't think push scan is necessary.
In either case, I don't think the answer is to add another TXT record key for a capability that can be implemented by a client.

Do some scans and check the sizes. I recently scanned 65 pages worth of reports to have a digital copy, and it fit in 8MB. That doesn't take a long time to send even over bad Wi-Fi/cellular links.
