Geolocation approaches are fundamentally broken if they assume networks are static.  The relationship of an address-location might change over long-ish timescales, but it does indeed change.  And an ASN doesn't necessarily align with a geography.  I don't see how ASN transfers materially change this situation.

I'm struck that all of these issues are effectively dealt with by using Whois.  This is true for IP prefixes as well as ASNs.  So I'm not sure I understand how you're applying these beyond their original context of address sharing.  It's certainly not clear to me why they're reasons to prohibit updating Whois records to reflect ASN transfers.  Can you explain further?
