In this comment: https://searchfox.org/mozilla-central/source/xpcom/ds/nsBaseHashtable.h#40-41

It is said that "this class manages simple data types that do not need construction or destruction."

This is startling to read, because it suggests we cannot use nsTArray or any other non-trivial type. However I believe what this comment is really saying is that it cannot hold types with non-trivial moves (things with intrusive pointers), similar to the constraint on nsTArray's own contents.
