It is used at a large and increasing scale. Some does escape. But my understanding is that a big source of atmospheric methane is wells, that are not properly sealed once they are exhausted for commercial use.
Not to mention the infamous cows that release a lot of methane. ;)

By "large scale", I mean for example if P2P methane rockets replace much of the airline industry (as SpaceX hopes for Starship), and/or if methane replaces fossil fuels in other industries. Methane itself can be carbon neutral, so leakage may be its biggest drawback.
