So the question is between `FEATURE_WRSR_EXT2` and `FEATURE_WRSR2`.
In reality your next patch CB:79460 needs this, when you get to testing.

Nikolai maybe you can help us with this? Thank you!

(I will get back to this after holidays)

Okay I see that the other chip has the same range too. Let's leave it for now, but maybe any of other reviewers knows why reducing the voltage range might be needed?
