 WARNING: If the deployer renounces administrative rights in favour of timelock itself, assigning new proposers or executors will require a timelocked operation. This means that if the accounts in charge of any of these two roles become unavailable, then the entire contract (and any contract it controls) becomes locked indefinitely.

 This process of bundling user operations involves several costs that the bundler must cover, including base transaction fees, calldata serialization, entrypoint execution, and paymaster context costs. To compensate for these expenses, bundlers use the `preVerificationGas` and `gasFees` fields to charge users appropriately.
 
-NOTE: Estimating `preVerificationGas` is not standardized as it varies based on network conditions such as gas prices and the size of the operation bundle.

 TIP: Although any Account that breaks such rules may still be processed by a private bundler, developers should keep in mind the centralization tradeoffs of relying on private infrastructure instead of _permissionless_ execution.
