Hi, this patch was marked as waiting on author since the beginning of the CF, most likely because it no longer applies (not sure). As there has been very little activity since then, I've marked it as returned with feedback. Feel free to re-submit an updated patch for 2020-03.
This definitely does not mean the feature is not desirable, but my feeling is most of the discussion happens on the other thread dealing with global temp tables [1] so maybe we should keep just that one and combine the efforts.
