Yes, it's a reasonable workaround. I believe Patreon also allows creators to "pause" their account, suspending payments for an indefinite amount of time. So, I could just keep the account paused, then unpause for a month when I make a video. Although, I believe that Patreon doesn't want the per-creation model themselves, since charging the same amount each month is simpler, and easier to project revenue, etc, so they are probably just bundling this unpopular change with the Apple announcement.
