Because heavy pages load worse for readers, especially on poorer connections. That’s basics of web development.

From usability standpoint, it’s better to have a page that doesn’t weigh 2.3 Mb just in HTML.

For the record, I don't think that the need to be able to build even longer pages justifies fulfilling this request. They can always split the pages, which is better for readability and usability.

Working demo is ready. Now it can stream completetions from OpenAI: https://github.com/skripnik/wikipedia-section-summaries

In comparison, this is some random short page from Russian Wikisource: https://ru.wikisource.org/wiki/%D0%95%D0%AD%D0%91%D0%95/%D0%A1%D0%BF%D0%B8%D1%86

This is one of the longest pages in Russian Wikisource: https://ru.wikisource.org/wiki/%D0%A4%D0%B8%D0%BD%D0%B8%D0%B0%D1%81_%D0%A4%D0%B8%D0%BD%D0%BD,_%D0%B8%D1%80%D0%BB%D0%B0%D0%BD%D0%B4%D1%81%D0%BA%D0%B8%D0%B9_%D1%87%D0%BB%D0%B5%D0%BD_%D0%BF%D0%B0%D1%80%D0%BB%D0%B0%D0%BC%D0%B5%D0%BD%D1%82%D0%B0_(%D0%A2%D1%80%D0%BE%D0%BB%D0%BB%D0%BE%D0%BF)/%D0%94%D0%9E

Another consideration: the alternative to a page with 4 MB of text is not a page with 1 MB of text, but rather 4 pages with 1 MB of text each.

More memory consumed everytime it is interacted with by the software.

User Vladis13 did a great job importing some public domain texts in Russian Wikisource. He also prepared a folder with texts that were too big: https://disk.yandex.ru/d/QjFXyEiY0t7Qvw

Ok, I didn't know that for Wikimedia wikis you use different kind of settings. But I assume it works like that: there is a variable $wgMaxArticleSize that you can tweak for each individual project, right?

Oh wow, this was open for more than a year ago. Why it hasn't been done yet?
