I know about the other third-party options out there, this is more to do with the native stuff that comes bundled from Apple. For years Snow Leopard has had notoriously bad NTFS read-write support hence it was disabled by default. We could enable it like this, but it was dangerous at best. So, has this improved in Lion, or is this still a neglected dangerous feature?

I haven't seen any credible reports that NTFS write support has improved with Lion. It was in Snow Leopard and still is disabled natively.
As, it's not supported by Apple, getting a good third party plug in to enable that feature is as mandatory with Lion as it was with Snow Leopard.
