Okay, just checked w/ KindleGen & KindleUnpack.
KindleGen dual mobis: OK
KindleGen dual mobis + KindleUnpack split: M7: OK; KF8: MEEP.

Notice the lack of either a proper asin, or a hash. Which is... bad.
In addition to that, those files have a crappy tiny thumbnail in cover view mode in the Library (since I did not sideload one, and can't anyway, due to said lack of ASIN or hash ;p).
For the record:
Shakespeare's Complete Works is a Calibre KF8. With a random UUID as ASIN
.
Life on the Mississippi is a KFX book (nearly) straight from Amazon. So, proper ASIN
.
Handfast is @dhdurgee's KF8 testcase. NULL ASIN
.
Macbeth is a KF8 split with KindleUnpack from a KindleGen dual mobi. NULL ASIN
.
Jane Eyre is a KindleGen dual mobi. Old style hash
.
----
TL;DR: Save a tree, put an ASIN in your KF8!
----
@dhdurgee: That there's one in the OPF is irrelevant, we're on a Kindle, we don't care about OPF/ePub
.
KindleGen will *never* put one in the Mobi metadata, that's what's important here
.
TL;DRē: @eschwartz recommended various ways of sanitizing a KF8 for the Kindle, I'd recommend doing that. And, if that's not already the case, it might be an interesting info for Sigil users to know?
