Links to SDL Documentation and Community sites are broken

Recent updates on the SDL documentation and community sites are breaking some older existing links from tridion stack exchange.

When will SDL have redirects in place to fix this please?

For example in "Preview for ECL in RichText"

https://tridion.stackexchange.com/a/17695/29

Link to SDL Docs "Styles Configuration"

https://docs.sdl.com/LiveContent/content/en-US/SDL%20Web-v5/GUID-D95860F7-15DF-4091-B24E-3539F7CB33C4

Just redirects to https://docs.sdl.com/home

"similar enchancement request about showing External Content previews to CMS users" https://community.sdl.com/solutions/content-management/tridion/sdl_web_ideas/i/sdl-web-ideas/srq-6149—ecl-implement-gettemplatefragment
