It is not ideal, no. The RAW pin first goes into a 3.3V voltage regulator whose dropout voltage is up to 200mV (worst case). That means that you would get around 3.1V out, and it wouldn't be properly regulated.
Oh, it would work, but the power won't be stable, which means that any analogue readings that you make that don't directly use the (shakily) ...

When additional resistors are added in parallel, which is what is going on when you add new I2C devices to the I2C bus, the overall resistor is lowered. This could cause a problem with devices that cannot provide enough current with a low pull-up resistance. Hence, the device will not function well when the pull-up resistance is lower than a specific value. ...

if you are using an Arduino, I recommend you to use the BPlib, it's a free arduino library that contains functions that are similar to the Keyboard.h.
The following link is from the Arduino website: https://www.arduino.cc/reference/en/libraries/bplib/
When you download the Lib, take a look at the examples given by the creator of the Library, all the example ...
