The reason is that you have not gotten any committer support for this
patch or attracted significant review, that I can see. On the contrary,
three committers have expressed doubts about all or some of the patch
and it doesn't seem to me that their issues have been addressed.
This is also a relatively new patch which makes large changes -- we
generally like to get those in earlier than the second-to-last CF.
I can only spend so much time looking at each patch, so Peter, Álvaro,
or Andres are welcome to jump in and let me know if I have it wrong.
What you need to be doing for PG13 is very specifically addressing
committer concerns and gathering a consensus that the behavior of this
patch is the way to go.
