Is there any reason to have tsfeatures https://github.com/Nixtla/tsfeatures when tsfresh https://github.com/blue-yonder/tsfresh already includes a lot more features?

Some features specialized on time series forecasting are not available on tsfresh. The tsfeatures project started as a complementary project to have an implementation of FFORMA in python. https://robjhyndman.com/publications/fforma/

tsfresh is generally clunky and old, there is a faster package lit there called tsflex.
