 9 months ago, I opened #15806, which was about documenting when -hT can be
 used. Ben created some patches to resolve this, but with GHC 8.6.3, I find
 the behavior is identical to 8.4.2, namely:

 * -hT is disallowed for executables built with profiling
 * the docs make no mention of this
 * when profiling is enabled, the list of options for heap profiling make
 no mention of -hT, making me question my sanity.

 Ben apparently fixed all of these, but perhaps it never got merged?
