I²C OUTPUT_OPEN_DRAIN ./. OPEN_DRAIN

hi we talk just in time the I²C glitch problem in arduino esp32 core. not tested just in time, but makes sense: at we have : gpio_set_direction(scl_io, GPIO_MODE_OUTPUT_OD); gpio_set_direction(sda_io, GPIO_MODE_OUTPUT_OD); to change it to OPEN_DRAIN only? gpio_set_direction(scl_io, GPIO_MODE_DEF_OD)...
