It's cool while it works. But these options are not going to be provided forever in newer hardware. Recent example I saw is the absense of AHCI option in new laptops (you now need additional drivers just to reinstall Windows manually). We need to keep developing software solutions to software problems.
Is it not disgraceful that you have to use a trick so some third party company doesn't install software you don't want on your hardware? I think that's appalling!
There doesn't have to be anything wrong with it, though I seem to remember that BitLocker isn't all that difficult to break if your passphrase isn't long enough. I just found it a bit weird because unlocking via TPM very much feels like the standard solution under Windows.
