What is the status of D dataframes?

[p.shkadzko]

Reading the "Rust Dataframe: Update 1" post on HN, I decided to 
check if D has something similar like pandas and stumbled upon "D 
Dataframes" https://github.com/kaleidicpublic/d_dataframes.

The README says "very early stage" but the last update was 3 
years ago. It's not like D doesn't have abandoned packages, 
plenty of them. I am just curious what happened?
