Yes, you may. Sorry about that, I'm fairly new here.

@DannyS712 Yes, that would be correct. Make it as global as possible, across skins and wikis, etc., but that's the general idea. Thanks for doing this!

From what I've seen, a good number of these pages have uncomplicated histories with single-digit numbers of missing revisions, so they can be imported by hand (by directly modifying the XML file with the new revisions and re-importing it if I'm not mistaken). On the other hand, there are some pages such as HomePage, with 418 missing revisions, that should most probably be imported with some sort of script or bot. (I know I'm saying that like it's something easy.)

Nope, the easiest way to do the imports is to import the XML dump into a separate MediaWiki database and use Special:Export from there to create the XML files, which can then be edited by hand, if necessary. That way there's no practical limit on the number of revisions that can be imported at a time. I've worked on a few pages this way, slowly. A few points though:
*I seem to be in the minority with this, but I really would prefer it if we only imported revisions where existing history (either on the English or Nostalgia Wikipedias) already went back to the 17th of August or earlier. I see gaps in history as potentially very confusing.
*We need to make sure usernames line up correctly on the English and August 2001 Wikipedias, including username changes (either by choice or through software changes like the "~enwiki" prefix). Local usernames should be preserved in all cases.
*We need to only import exactly the revisions we need, per T175357 (which still applies here).
*All an article's revisions should ideally be in one place ... a lot of cut-and-paste moves were made back in 2001!
