Bitcoin Core – a miner for non-standard transactions

I have Bitcoin Core IsStandard() To prevent non-standard transactions from being broadcast (unless they are mined blocks), check out v0.9(?).
I would like to know if there are currently any mining pools or miners that process non-standard transactions. This means you are running a non-default configuration that allows non-standard transactions to be submitted using: sendrawtransaction (or other methods).
When we say non-standard, it means the transaction will be rejected. Non-standard input (i.e. an input that returns false when evaluated with) IsStandard()).
I already understand it testnet It’s more generous in this sense, but I’m particularly interested in miners. mainnet.
Note: This question is for academic purposes in support of a paper I am writing.
