What would be nice?

estimate_gas on Op doesn't include underlying l1 costs

https://optimistic.etherscan.io/address/0x420000000000000000000000000000000000000F#readProxyContract

The above link has
rawhex = signed_tx.rawTransaction.hex()
l1BaseFee = opGas.functions.l1BaseFee().call()
overhead = opGas.functions.overhead().call()
scalar = opGas.functions.scalar().call()/1000000
gasPrice = opGas.functions.gasPrice().call()
l1Fee = opGas.functions.getL1Fee(rawhex).call()
l1GasUsed = opGas.functions.getL1GasUsed(rawhex).call()

Would be dope if instead of users having to delve deep into l2 developer docs and track down the in's and outs
of how this stuff worked, you guys could work your wizardry and simplify things a bit.

I'm guessing the same goes for arb and any other l2's but the only one I'm wrestling with is Op.
Perhaps estimate_gas could look for chain id, and then magic the appropriate information out
respectively.

Please include any of the following that are applicable:

• The code which produced the error
• The full output of the error
• What type of node you were connecting to.

How can it be fixed?

Fill this section in if you know how this could or should be fixed.
