So the author wants a configuration, where I can either run the program with --foo-timeout=5 --bar-timeout=10 or with --no-timeouts which disables the timeouts for both too and bar. I don't know the author's entire usecase, but it seems odd that you would specifically NOT want the user to only disable one timeout, but keep all the others active. Unless there is a real reason for this, the more logical design for me would be to treat --foo-timeout=0 or something as the setting to disable timeout foo. Not sure if argparse supports aliases, but if it does, --no-timeouts could then be defined as an alias for "--foo-timeout=0 --bar-timeout=0 --baz-timeout=0" etc etc.
