After a lengthy bring-up debug session, I noticed the #SSD1303 not quite behaving as I expected.
Pin D2 (SDA_out, which "should be left open" in #SPI mode) was not staying high all the time, like I had measured previously.
Rather it was shifting out some kind of gibberish data.
This was not compatible with my tested idea of "just putting a diode between SDA_out and SDA_in (D1)", to still allow I2C-lows through in #I2C mode, but block the constant* high signal in SPI mode.
