From what I could read on the web, the Internet Archive is threatened by a massive lawsuit:

It means there's a risk that a lot of manga/manhua/manhwa will disappear.
Although the Internet Archive technically have raws (which MD don't allow users to upload), some of these may be series that are not available elsewhere (for example old stuff out of print, made by bankrupt publishers, and not purchasable online).
I suggest MD might ask the Internet Archive for such series.
