The package was made by the previous maintainer who didn't want to rely on other people. We simply use the "normal" package, and I changed all depending packages to depend on opencv3-opt.

OK, thank you for your explanation. Given that - the two packages appear to be duplicates, - opencv3-opt is the (very slightly) older package with more votes, - no other packages depend on ros-melodic-opencv3 and - I have seen no disagreement with the merge request in the month it has been open, I am going to accept it.
