(I also tested libopencm3, and it can also re-flash without having to hold down the reset button.
AHA! I found out. Problem was actually solved a month ago and described here: SWD/JTAG disabled by the flashing? · Issue #61 · platformio/platform-ststm32 · GitHub

With above flag it works fine, regardless of whether reset_config none is specified.
