Unnecessary and terrible idea. The position of the spin on will dump oil all over the engine.

A cartridge filter is great and I spill zero oil during a change.

Appears to me that no "ADV" is even needed. They say in that link that there isn't one, but the way this describes the system, it's not needed.

"A chain-driven (single chain), vane-type variable displacement oil pump adjusts the flow rate and pressure as commanded by the engine management system, which uses a solenoid to drive the pump into low or high pressure mode. For example, below 3,500 rpm, the pump conserves energy by using low pressure; at speeds over 3,500 rpm, the pump switches to high pressure.

A force balance mechanism inside the oil pump adjusts the size of the pumping chambers to alter oil flow. If the oil is cold, the pump reduces the size of the internal chambers. When the oil is hot and thinner, more oil is needed, and a spring increases the size of the pump chambers. This also saves energy.

The pump is driven at a 1:1 drive ratio; its location under the block is more efficient than an on-crankshaft location. An internal, mechanical ball-and-spring relief valve dumps oil into the sump when needed, for conditions such as a cold start with high engine speed. Both pump and pressure regulation solenoid are non-serviceable. Removing the oil filter cap from the housing allows oil to drain from the oil filter cavity into to the crankcase".

So - oil doesn't drain out of the filter normally. And IMO, if there was a problem with oil not being there or where and when needed, there are parts that would sure know about it.
