The Sea Of Thieves version of Melee Island makes up a few short alleys behind the church and store.
But it only puts a short covered archway between the clocktower and High Street, which according to the above discussion can't be entirely right. It does at least make up a short path between the Scumm Bar and Low Street.
On the whole though it seems at least a loving recreation, and an accurate-enough one too, as far as I know.
I'm sure people with more intimate knowledge of the games and island will be more than happy to correct me though
