@mro There is a suggested FEP to include the WebFinger resource in the actor document: https://codeberg.org/fediverse/fep/src/branch/main/fep/2c59/fep-2c59.md But I have not seen it implemented anywhere. In the meantime, the hacky approach works and is reasonably popular. 😄
I don't want to push you into supporting something you don't want to support. Just keep in mind that your software is showing different account handles than Mastodon for some users.
Do you want me to add Seppo to the overview table anyway?
