In the latest version of Dagster I'm getting warnings for passing an io_manager (the python object) to io_manager_key parameter in @asset (because it expects a string input), but I'm also getting warnings for passing it to io_makager_def (because it's experimental) Which of the two is preferable?

hi @Mycchaka Kleinbort! the behavior of passing an io manager into

io_manager_def

is (subjectively) unlikely to change, and I'd recommend going that route.
