What's the impact on the file size?

Forgive me, as I'm not a heavy Voice Memos user, but I'm a bit confused by problem statement.

Voice Memos seem to be ordered chronologically, and named after the location where they were taken (unless manually named), which seems decent unless you star getting a ton.

From the Voice Memos app I can share them to Messages, Mail, etc. Is the issue that you wanted to be able to select a voice memo to share from within Messages, instead of the other way around? Or is this more for posting audio only to social networks that only support video, and having a waveform instead of a random video of something else?
