I have created the PR https://github.com/vim/vim/pull/13419 to support this.
Can you try out the diff in the PR and let me know if you see any issues?

:-) I have found the following workaround: I pass the buffer number to
the callback, then I iterate over each parsed line and manually set the
buffer:
def Callback(channel: channel, msg: string, bufnr: number, ...)
[...]
var what = getqflist({"lines": [msg], "efm": efm})
for item in what.items
item["bufnr"] = bufnr
endfor
setloclist(winid, what.items, "a")
enddef
Life.

There is a item in the todo list for more than 20 years now for this:
- Add %b to 'errorformat': buffer number. (Yegappan Lakshmanan / Suresh
