**Feature summary**
`$wgDisableHardRedirects` prevents two types of redirects from being "hard redirects," and turns them into "soft redirects," which require another click:
# Interwiki redirects to other wikis
# Redirects to special pages
These are two different things. It's quite possible a wiki wishes to allow one, but not the other. Shortcuts to special pages such as [[SP:RC]] can be very useful. I don't really understand why they're not allowed. Redirects to certain problematic pages like [[Special:LogOut]] are prohibited, regardless.
{T326054} would be straightforward to fix.
I can understand why interwiki redirects would be stopped. Someone viewing an independent 3rd party wiki doesn't expect to be whisked off to Wikipedia after clicking a blue link.
This is quite an old setting (from 2006), IMIIC, and has worked for 20 years, but might need a rethink.
**Proposal**
This configuration should be split into two different configurations, or at least one of them split off into something like:
- `$wgDisableHardRedirectsToSpecialPages`
- `$wgDisableHardInterWikiRedirects`
Needs discussion.
