Potlatch2 has the ability to read appropriately-preprocessed Vector
Background layers, which allows mappers to pick and choose which bits
of a datasource to "import" and where to simply copy tags over. It's a
promising approach to follow.

I've found this in swathes of south London - pairs of naptan and
non-naptan bus stops along major roads, suggesting that it's been
years of things not being fixed up before I noticed. I was quite
surprised to see that given that London is one of our most
actively-mapped areas!
