/*
 * I2C seems to randomly drop keystrokes. Not sure why. It seems a bit like
 * https://github.com/qmk/qmk_firmware/issues/5037, but that issue is closed,
 * and our problems happen even with underglow disabled.
 *
 * This issue occurs with multiple TRRS cables of different lengths from
 * different companies, so it's most likely not a cable issue.  It may be that
 * we are running into issues with long I2C runs, in which case stronger
 * pull-up resistors might help:

 * For now, just don't use I2C.
