If we are exposing this we at least need a note similar to the one in https://nodejs.org/api/v8.html#v8_v8_getheapspacestatistics
Neither the ordering of heap spaces, nor the availability of a heap space can be guaranteed as the statistics are provided via the V8 GetHeapSpaceStatistics function and may change from one V8 version to the next.
As compared to the GC kind the flags here seem to be even less stable.
This also lacks explanation and they are less self-explanatory compared to the gc kinds. I guess we could link to the v8 docs of GCCallbackFlags at least for reference.
