dstat was basically presumed dead due to lack of upstream activity. I recall the internal discussion was something like

A: "Whoa, there is no dstat in RHEL8? Customers are gonna complain."

B: "Yes, it's because it's Python 2 only and upstream is dead. Tell customers to use PCP"

A: "Srsly? Nobody thinks of the scripts? Besides, dstat output is so nice."

C: "Well, there is some toy example to print pcp data in dstat format."

A: "Do we really want to tell customers 'there is a toy example'?"

C: "Give me a day or two to pimp it up."

And then C got a bit carried away. :-)

Why would you try to contact someone who's abandoned the project?

Maybe because it is the nice thing to do?

And it's not like I have disappeared from the face of the earth. I am quite active on GitHub.
