Wouldn't you have to do the same if you pass in the env as an object?

I only need to create the env object and pass it to serialize, reusing the same global MarkdownSerializer.

Ah, I see, it's an argument to serialize. Still, this seems to address a highly specific use case that's easily enough worked around by putting the values you need to access in some shared variable, so I don't think this needs to be in the library.
