Dropping MOBI Support on Send to Kindle Apps

Last week the news broke about now allowing Kindle users to send ePub files to Kindles by email, and how the Send to Kindle apps will be getting ePub support later in 2022 as well. There was also a smaller news story that was revealed at the same time that's worth discussing as well.
