Details

Current API does not allow writes from specified offset. Technically setPosition could be used it perform writes from specific offset, but that can't be used for concurrent writes at different offsets. We are trying to bring distributed web protocol like Dat, IPFS, SSB into Firefox via extensions and as they replicate data from p2p networks they often write at different offsets in parallel, introducing scheduling would greatly reduce they're performance. I also seems that there OS.File even creates bindings for (pwrite)[https://github.com/mozilla/gecko-dev/blob/3c701634e0abd5c7f7ce89074b84eb96759ea844/toolkit/components/osfile/modules/osfile_unix_back.jsm#L421-L425] but they don't seem to exposed. I'll be willing to do the work if someone is willing to mentor.
Summary: Support offset on write → Allow passing offset for read / write operations
