Yep, it’s pretty odd scenario, by adding more features while it has a lot of issues as well such as ease of use like @TopBagon point.
Also for @drjellyiam.
The way I see it deprecated just means you can still use it, but if it breaks or cannot do something new and advanced (ex: Rigidity enabled) you cannot complain about it.
Even then they still do fix it, such as the body gyro case math.huge in 2021 even though the new bodymovers were released in 2017. So yeah it’s pretty odd I guess it’s because even advanced developers like Jailbreak still use BodyGyro’s and well they work.
