This is a use case worth covering for any CMS, in my opinion. Currently
when one doesn't want to maintain a CMS any longer I'm forced to tell
them to crawl with wget-warc/wpull (possibly via ArchiveTeam), submit to
Internet Archive and then somehow redirect users. Few CMS seem to care
about it though.
In practice the only "official" solutions we have are:
+ any webserver
+ kiwix-serve (mwoffliner via Parsoid)
, it seems WMF has no
interest in providing a static HTML format which is directly usable.
