White R16 is common responce, black blocks Q16, white hanes S15 etc. Very much the same outcome what white would expect from invading to 3-3 under a 4-4 stone. Assuming white “only” wants to make life in the corner since she invaded R17 instead some other move like Q17 or P16

Common in your experience? It hasn’t been played by professionals but it might be worth including as a reference.
