That's awesome! However, it WILL result in stripe attracting a LOT of the crappy billers (ie, folks who mislead / make customer unhappy etc). If your business is < 1% refunds, no worry if fees stay. A fair number of business have just 1 or 2 refunds PER YEAR.

Other business obviously have MUCH higher refund rates (sneaky autobill businesses etc). For these loosing 5% on the refunds matters if they have a lot of refunds, so they'll be very tempted by no costs if you autobill and get caught. They'll just autorenew everyone, autosign up and then be VERY good about refunds to avoid chargebacks. Even if just 30% of customers don't catch a few months you end up with real money.

Of course, CUSTOMERS may hate these players, but stripe I guess is focused on what works for the businesses generating lots of refunds.
