Something like this could be implemented, but Hydra is using argparse for a few basic flags (--help, --run, --cfg etc) and argparse would not like us passing arbitrary undefined flags.

Philosophically speaking, I am not seeing a big advantage for Hydra overrides syntax to line up with getopt. What it does is different. For example, unlike with getopt - you MUST specify a value with every override, there is no support for flags like --verbose. it would have to be verbose=true, the reason is that those are editing the configuration object, and in 99% of the cases you want to put in a value and not default to true.

Also, you should be thinking of those command line arguments as editing a complex object. db.driver=mysql means: in the db map, change value of the driver key to mysql.
