I don't see how the situation benefits from calling something the "main interpreter". Subinterpreters can be a way to take something non-thread-safe and make it thread-safe, because in an interpreter-per-thread scheme, most of the state, like module globals, are thread-local. (Well, this doesn't help for async concurrency, but anyway.)
You could have a privileged C extension that is only imported in the main interpreter: if get_current_interp() is main_interp(): from _decimal import * else: from _pydecimal import * This is of course only attractive if importing the interpreters module and calling these functions has minimal overhead.
