From my understanding, it is not possible, e.g., we can not seek because we do now know offset upfront decompressing, also from what I see, built-in go zip also uses ReadCloser
.
PS: yes, theoretically we can work with offsets of compressed file but still it seems like even native 7z libs does not have this which makes me believe it wont be doable

You're right, it's not really possible.
You can sort of implement seeking, but only to the same offset or further forward in the file by just reading and discarding bytes, so it's not any more efficient as you still do the same amount of I/O, there's no way to just jump to a particular offset.
