-> It has long annoyed me that [matrix.to](https://matrix.to) URLs are in the unfortunate situation of being [specified](https://spec.matrix.org/latest/appendices/#matrix-uri-scheme) following [RFC 3986](https://tools.ietf.org/html/rfc3986), while Matrix room aliases use `#` as their "sigil". The nice part is that the fallback in many browsers and probably URL parsers allows someone to type in the literal ID after `https://matrix.to/#/` in a human readable/type-able way: `https://matrix.to/#/#matrix:matrix.org` and it will work. However that does not actually comply with the RFC spec for URLs, which mandates URL-encoding ("percent-encoding") for some special characters, including the `#`. The practical impact of this is that in some situations, URL parsers my stumble and misinterpret matrix.to URLs. We commonly see this at the Website & Content WG when writing YouTube descriptions: the second "illegal" `#` will be interpreted as a hashtag instead, breaking the link. I find this particularly annoying as some implementations, including Element and <https://matrix.to> itself actually prefer to generate "illegal" links. This has been a topic of discussion before, but so far has not been accepted.

 > Meanwhile, we also have the [`matrix:` URI scheme](https://spec.matrix.org/latest/appendices/#matrix-uri-scheme) registered with IANA. Instead of the sigils, it uses letters like `r/` for aliases: `matrix:r/matrix:matrix.org`. So at Matrix Community Summit last weekend, we had the idea to deprecate using sigils in matrix.to fragments altogether and replace them with `matrix:` URI style word characters. You can find all this packaged as [MSC4481](https://github.com/matrix-org/matrix-spec-proposals/pull/4481) including an implementation for <https://matrix.to>. Please feel free to test or implement in your own client. Thanks to all involved in the discussion and helping the implementation!
