Since we are in the fediverse, I think it would be convenient to have a fediverse-wide resolvable fediverse URI scheme, that would look like so:
fediverse://
edit: Found a relevant FEP: https://codeberg.org/fediverse/fep/src/branch/main/fep/07d7/fep-07d7.md
The disadvantage is, Reddit and other platforms will never add support for [fediverse hyperlink](fediverse://example.com/post/1337)
Markdown syntax, or even start blocking it (they can already block known Fediverse domains but there would be backlash if they did).
