It doesn't output the final result that you'd expect from a human professional, but it does seem to be well into the professional level of tools. And for cheaper productions you could use it directly.
Not ready for strait output on a special effects driven big budget show who are more then happy to pay someone to sit there for days rotoscoping. These are not the only professionals wanting to use special effects. Would anyone complain if MrBeast's video got the blend of the texture of his cloaths a bit rough?
I mean, having done quite a bit of rotoscoping work in high school, if you can start from the output of this plugin and refine a little, you’re absolutely still saving hours. It was still most of the way there.
I think that's a big chunk that people are missing. This tool ac get you from zero to 80%-90% for most shots in a handful of seconds.
