E30 M3 - shim oil pump , oil pan baffle needed
e36 M3 - safety wire oil pump
E46 M3 - bearings, oil pump , BMW extended warranty while in production ..
E90 M3 - replace bearings as PM? Etc
F80 M.. - crank Issue you mentioned
G80 M... ???
So... more than likely S58 will develop some sort of character flaw in the next 3-5 years ..
Don't sweat the technique ..

E36 Euro motor did not have this issue. On the other hand,
S50B30 euro - oil starvation on high lateral G applications due to single oil pickup(fixed at the release of S50B32)
S50B32 euro - con rod bolt stretching on sustained high rpm (7600 rpm)
So yeah. No motor without "issue" thus far.
