They almost certainly run into these issues, but like most of the community, they probably think the cost is well worth bearing, given the advantages the language gives you.
Once you're used to the way it works, and if you're using well-maintained libraries, I find that it's really not such a big deal. Though it's always awkward to have transitive dependency conflicts, and those are best avoided if possible.
Wonder if they've run into these issues with the language though
