Recently I downloaded the old table for en. I would like to keep a reasonably up-to-date copy of it around for history queries. You can see [[Wikipedia:Another list of Wikipedians by date of arrival]] for the sort of stuff that interests me. I think it helps the project.
Anyway, I know the subject of incremental updates has come up in the past, and has been ignored because it's fiddly to do and no one cares much.
It would, however, be extremely helpful to me if even the minor measure of splitting the files before compression rather than after were taken. That way I could download the last file or two, and cut and paste the files based on oldid. Please....
Thanks
