Obviously we all have different use cases and I welcome this media type. Shooting 4K video is about 10% of my work. The capacity of the cards really does not bother me that much. I'll probably get a CFExpress card but at the moment, the SanDisk reader is just another thing to have to carry with me, and remember to pack away if I'm shifting hotel. Then I prep my gear for the next day and only then do I look at the results of my days shooting. Over the past 30+ years, I have made sure that my devices get their batteries charged either before I get fed or while I am doing so. I can go and shower/eat etc and by the time I'm done, the copy will be done and I can get down to work. At the same time, the Camera will be charged.
My workflow is at the end of the day, connect the camera to the Mac and start the transfer. I'm really not that bothered by the camera to compter data transfer rates.
