- I am looking for input from experts on the current theoretical status of hypothesized Generic Objects of Dark Energy

I have come across some online references to Generic Objects of Dark Energy (GEODEs). They are briefly described in this Wikipedia article:

https://en.wikipedia.org/wiki/Generic_object_of_dark_energy

The only reference from that article that I have been able to find online is this paper:

https://arxiv.org/pdf/1904.03781v2.pdf

The paper refers to several previously proposed solutions, including the "de Sitter sphere" (Gliner 1966), which looks to me like a claimed spherical region of de Sitter space surrounded by a Schwarzschild vacuum, which seems obviously unstable to me (the surface area of the de Sitter region would not be constant in time), but I have been unable to find the original paper online or any other reference that shows the actual math of the solution.

I am wondering if any experts can give useful references concerning the current theoretical status of GEODEs or of any particular solutions in this area.
