I wonder if the plan is to implement him in the next Nook upgrade that we don't have yet.
Wow, I bought over 400 and change them out at times, and still need hundreds.Honestly, I wish Leif would have his own shop solely so he can be taken out of the visitor rotation. I already purchased a good chunk of bushes of all types and some cosmos flower seeds from him when he visited, although I've only used 4 bushes so far. So I just ignore him now whenever he comes to my island, which sucks since that's a spot that could instead be used for somebody I'd interact with (mainly Redd).
