Currently, it redirects to /w/index.php?title=foo , which results in stale cache:

Still not resolved, I see instances when this fix works on live site and some when it doesn't.
Max, can you give examples of where this is not working? One that I found quickly was on pages like:

Is this a namespace related issue?

Is this a namespace related issue?
Maybe, I'll need to investigate this.
I think I've resolved this for desktop -> mobile requests that happen on sites that have a mobile URL template defined (eg the WMF cluster): https://gerrit.wikimedia.org/r/#/c/36809/1
This should make all 'mobile view' links canonical, all the time. This should work fine on the WMF cluster which passes all .m traffic through the mobile varnish servers, which will always result in a mobile view (even without ?mobileaction=toggle_mobile_view).
This approach will not work in the reverse (mobile -> desktop view) because we need the mobileaction query param for non-js browsers to set the stopMobileRedirect cookie.
