dvc experiments checkout: option to select the best experiment regarding one metric

I had an idea while trying the new experiment feature. For the use case of grid-search or hyper-parameter optimization, could we imagine an option for dvc experiments checkout to checkout the best experiment regarding one of the metrics? Something like dvc experiments checkout --best metrics.json:accuracy. With an option like this, you can run (manually or automatically) a lot of experiments and ask dvc to return the best experiment, which can be then commited to git. Or instead of --best, it could be --lowest or --highest to take into account that some metrics should be minimized and some others maximized.

Start with the dvc experiments checkout entry point and trace how experiment metrics are selected and compared. Clarify whether the interface should support --best, --lowest, or --highest, then define behavior for metrics.json:accuracy and metric direction before implementing tests and the checkout result.
