Using Abseil vs. Directly calling main()?

I've been using the vanilla

def main():
    # Do stuff


if __name__ == '__main__':
    main()

but recently saw people doing

from absl import app

def main(_):
    # Do things

if __name__ == '__main__':
    app.run(main)

Abseil provides flags.FLAGS, but I've been using ArgumentParser, which works perfectly fine, so there is no win for Abseil in this aspect.

Then, why bother go the Abseil route?
