The consequences are just more severe vs a blown shock or ac stops blowing cold.

There are identified weak spots in vanos (BMW underengineering) and solutions for them. Most of the time it's a when and not if.

3, 4, 5 owner cars could have had these issues addressed, there were solutions out there before Beijan, with VAC, Turbotoy, etc.

Sorry, but your comment is subjective. Do you have the CAD files from BMW of the VANOS tabs? Have you performed materials analysis on the hub, bolts, or tabs? No one really knows why the tabs fail. Putting stronger tabs is seen by some as a solution when I see a bandaid instead. Sure, luckily no one with a "bulletproof" VANOS has reported a failure, but it is still a car part.

These are documented post factum.

Based on work done by Beisan and others, we now know that there is a .2mm extra clearance between the tab and the oil pump disc hole which slaps around there while vanos is sitting at 115 bar (not psi).

We also know that the bolts back out because they were not threadlocked, not because the original ones are weak (meaning you don't have to buy beefier bolts, just get oem and locktite).

Have you done some analysis to share with us that makes you think it's a bandaid?

Although... the way you state it, it is not stronger tabs that are a solution...
You don't just put stronger tabs in, since the problem with the tabs is the extra clearance. The solution is either keeping same size tabs (reuse a hub that has both tabs intact) and get a redrilled pump disc with smaller holes (ala Beisan). Conversely, you can get a hub that is redesigned with bigger tabs (Turbotoy, VAC, etc) to take up the clearance and just reuse the same oil pump disc holes.
