Yes. I also have had my welded brake concoction in there for 4 years or so (I think you've seen my thread on that).
But in germany they have TüV and that even checks matching materials (so they also coulndt fit an aluminium spacer in there, it had to be iron).
If you want to deviate from that you have to have a TüV engineer write a report on that (like the reports you can download at german tuning products like KW).
Where I live we just have an annual checkup where the car gets onto a brake tester and they measure brake force etc (and obviously check wear) but if thats within boundries, its OK (so more a real life test than a theoretical evalutation). We do have a minimum requirement in how much brake force should be applied with the emergency brake (and if its in balance left/right).
And BMW emergency brakes are rubbish anyway compared to a lot of other brands.
But I like the idea to adapt the rotor to the factory spec.
