feature request: load multiple `.env` file before running a command

I have different configuration for my application that I intend to be composable. For example imagine I have env files with config values for database server hosts, and other env files with user credentials. I want to choose a combination of the two. I try to do something like

dotenv -f host_config.env -f user_credentials.env run bash do_things_with_db.sh

However it seems that only the last file is taken into account. I think this would be a useful feature to be able to load multiple files. What do you people think about it?

Start at the dotenv command-line entry point and inspect how repeated -f options are parsed and loaded. Reproduce the example with host_config.env and user_credentials.env, then verify that values from both files are available with the established precedence behavior.
