user3029: There are a bunch of encoded messages in the first taproot enabled block in op_return outputs. What is encoded there?

user47827: I don't know so alternative answers are welcome!
If you look at the coinbase transaction in the block 709632 (mined by F2Pool) where full nodes started enforcing Taproot rules there is a scriptSig and 4 OP_RETURNs.
The scriptSig is:
OP_PUSHBYTES_3 00d40a OP_PUSHBYTES_44 fabe6d6db2182a1a8634a5b5c8e4c9102f69b795db3d02e80064a0b007408cca80f68dc110000000f09f909f OP_PUSHBYTES_8 2f4632506f6f6c2f OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_0 OP_PUSHBYTES_5 00de920100
I don't know what the messages are in the OP_RETURNs though one of the OP_RETURNs is presumably used for the RSK sidechain as it refers to RSKBLOCK.
