I think most will agree that Luffy’s Haki is still not up to par with Shanks and this is a Shanks that will most likely lose to Teach. How many more fights does Luffy have till he fights Teach? & would simply just fighting strong enemies progressively be enough to make up for that gap? Garp for instance used to tango with the Pirate King & WB and even his Haki doesn’t seem to be as gassed up as Shanks is. So likelihood is that combat alone will not get Luffy to Shanks’ Haki level. Plus we’ve seen Shanks use some wifi type haki from outside an island to pinpoint & antagonize Greenbull so there still seems to be be more applications of it.
Regardless of whether Gaban turns out to the one that teaches him, I personally don’t think Luffy’s Haki training is over just yet
