There is libzstd-seek[1] which implements one convention[2] and also ZRA[3] which implements its own thing (apparently?) and then there’s the splittability discussion[4]... Clearly people want seekability, clearly the Zstandard maintainers do not want to get locked into a suboptimal solution. But I have to join this question: I can haz zstd seeks plz?
