hT profiling option
The docs indicate that you can pass -hT as an RTS option for memory profiling "by heap closure type". However, GHC 8.4.2 claims invalid heap profile options: -hT, and this option is not listed among the usage options printed with the error.
The user guide for GHC 8.2.2 also mentions -hT, and I believe that GHC-8.2.2 also did not permit the option.
