Then which series have you been following exactly? This chapter alone has been hammering steadily on this connection and this is not the first time during this arc. In fact you can trace it all the way back to the Thriller Bark arc where Zoro fought Ryuuma and obtained his sword. A sword that has been shown being an element of importance to the development of the current plot, something that was already hinted at during the Punk Hazard arc when Kinemon lost it when he saw Zoro wielding Shuusui. The fact that Ryuuma is a recycled character from an earlier story of Oda that served as Zoro's prototype, only gives this an even deeper dimension. Yes, this was 'out of the current story', but it establishes a connection nonetheless. In particular because he build an entire arc around it that was hyped for years and not merely used Ryuuma's character as a one-time easter egg.
Now I don't know how far the anime currently is as I haven't seen it in a while, but in the end the anime just follows the manga and I know several of the things I just explained already happened.
Lastly Oda said this in vol 92's SBS:
D: In Ch. 909, was the carpenter boss that appeared in Wano the same one that was introduced in the Volume 7 SBS, Minatoma-san? P.N. Yacchi
O: Yes he is!! Back then, he was fixing the broken door to the bar in Foosha Village. He was introduced as Carpenter Minatomo-san, exclaiming "Who did this!?". And now, he somehow ended up in the New World in the closed bordered country of Wano! Isn't that weird!? That's right, they actually aren't the same person! They have the same last name because they're related by blood. The fact of the matter is, a ship from Wano reached East Blue a few decades ago.
One of the descendants of someone on that ship is a person that everybody is familiar with...
This part might be featured later in the main story so I won't mention any more than that. It isn't going to be a major plot line, it will just be a minor story.
Granted, it doesn't explicitly say Zoro. But face it, of all the possible candidates Zoro is by far the most likely one.
So manga check ✔︎, anime check ✔︎and paratextual check ✔︎
Then the only question remains why you ever made this non-sensical remark in the first place as most of this isn't brand-new information? My incentive was that by now we've reached a point that the characters themselves, whether it be Zoro himself or one of the Wano citizens, should have grown some awareness, yes they seemingly pass this off as a coincidence.
