Hi Maciej,

there is no documentation for it (besides in the code itself) because it's
an experimental flag. What would you expect allow-lateness to do outside
the context of a window? Maybe you'd also be interested in
CURRENT_WATERMARK()[1][2] which will be released with 1.14 and allows some
level of late data handling.
