Will Twitter delisting require a governance vote?

Hi all,

According to Mirror’s docs, a mAsset can be delisted if a procedure is “initiated by the oracle feeder” (Mirrored Assets (mAssets) - mirror).

If the Twitter deal closes as expected and Twitter stock is delisted from the stock market in the coming weeks/months, do we need a governance poll to delist mTWTR from Mirror or will it happen automatically? Or do we need the oracle feeder to do something? (And if so, how does it work?)

Finally, does someone know if the same answers apply to a stock split event?

I am trying to understand if there is a risk for the protocol to not work as intended here if, for example, a governance vote is required and a whale decides to vote maliciously against the proposal.
