There's a ticket for removing
mobile.wikipedia.org and
wap.wikipedia.org
domains/subdomains, which are legacy domain names superceded by
m.wikipedia.org and its subdomains.
https://phabricator.wikimedia.org/T104942
The rationale for the removal of these legacy domain names is to help
support HSTS preloading in browsers with the existing TLS SAN cert.
After review of the ticket, can anyone think of a compelling reason to keep
those old domain names?
I'm going to open a separate thread on mobile-l about this given this is
more mobile-targeted, yet some people only operate on one of wikitech-l or
mobile-l.
