The changes does a good job on better code organization and adding more strict type comparison. But I've left some comments that could improve this PR.

Are we allowed to use Revamp? I'm still not sure about this.

IDK but this is what actually fit the changes done here. * Tweak would mean small change. * Change would also fit.

I see the code changes that it's intended to not save the zip code. What do you think if we put on the description of this PR and also put that on the changelog at least. I think the user should know about this. And potentially, we should ask this to A8C team too.
Yes, I'll reach out to change Woo Tax documentation and explain there that ZIP is not used in Tax Jurisdictions. Before that I want to have our internal validation that this change is good. |

It seems the jurisdiction cache key generation differs between where it's set and where it's retrieved :
The GET (get_jurisdictions line 722):
$key = 'tj_jurisdictions_' . md5( strtoupper( implode( '', $location ) . $customer->get_shipping_address() ) );This line uses hash('md5', ...) while GET uses md5(), these produce the same result, but the inputs are completely different
I think using
$location['to_country'] . $location['to_state'] . $location['to_zip'] . $location['to_city'] . $location['to_street'] )Is safer that $customer->get_shipping_address() since this can be filtered
