This delay applies to any data transfer on I2C bus.
For example 1kB data read with per-byte access (which happens if environment is stored in I2C EEPROM) takes more than 10 seconds.
Moreover data bus driver has to care about bus state and data transfer, but not about internal states of attached devices.
