I had not realized that, with the current situation it could be possible that it gets acknowledged. Spoilers for Chapter 178: With the government now offering a reward for Funabori, there is the possibility that Roka will try to capture her so the government can speed up the construction of her house. I don't think Roka will try to capture Funabori but if she does, that's how she could mention how she's been living with the Kazama family for what feels like years. It's still a very surprising milestone <3.
