So I used the Kindle Previewer to convert the epub, then split it into an azw3 and a mobi using KindleUnpack. I was hoping that I could just send the kf8 format, since the formatting in the kf7 version was a bit off
But XXX.azw3 or the same file renamed as XXX.mobi also were rejected. I don't know if the latter would have been delivered if my friend had a newer Kindle.
The omnibus XXX.mobi containing both formats worked. I'm pretty sure the dumbed down kf7 mobi would also work.
So, no backdoor conversions via email then.

No impoliteness, just saying it is sometimes easier and saves time to ask whether other people have performed the same experiments.
You aren't exactly the first person to have wanted to send AZW3.
MR members have discovered through trial and error that dual-MOBI works and unlocks AZW3 on supported devices (while sending the legacy MOBI to devices that do not support AZW3).
MOBI also works, as Amazon documents.
AZW3 will not work, I am guessing because Amazon doesn't want you to end up with a book that doesn't support older devices.
This is also why you can upload old-MOBI or dual-MOBI to KDP, but not AZW3.
(At least, I have heard that uploading old MOBI still works, but I don't know why anyone would want to...)
...
Renaming *.azw3 to *.mobi does not change the actual contents of the file, so it won't work. Any more than Amazon will accept corrupted files that have the *.mobi extension.
Because as far as MOBI is concerned, AZW3 is
not MOBI, so it must be corrupted somehow.
