Questions about the Powpeg

I read in the RSK docs that:

As of January 2020, the Powpeg comprises 12 well-known, and highly secure pegnatories.

Is the Powpeg still controlled by 12 pegnatories? What is the m-of-n multisig scheme they are using? 7-of-12 or something else?

The multisig scheme for the PowPeg is half + 1 of the total number of pegnatories. So it’s as you say, 7-of-12.
