Comment (by bgamari):

 I'm confused; `+RTS -hT` works for me under both GHC 8.4.2 and 8.2.2 and
 indeed produces a `.hp` file after the program finishes.

 Are you perhaps building with profiling enabled? Do note that `-hT` is
 only available when *not* built with profiling (although admittedly it's
 not clear to me why this must be the case).
