Perhaps the most straightforward fix would be to simply refrain from drawing any current at all from the vehicle's main battery while parked. The alarm and any other standby processes should run from a 12-volt motorcycle battery or something, which is recharged during driving, and can be jumped like any other car battery if allowed to go dead.
That wouldn't fix the Li-ion self-discharge problem completely, but it could provide as much as a few months' worth of margin.
In any case it's batshit insane to leave early adopters stuck with a $40,000 bill for your lack of engineering foresight. That was the real surprise in the article.
