Now on this, I completely agree with you. You can generate instance-neutral links on Piefed by putting an explanation mark in front of text: !piefed_meta@piefed.social - and it will be clickable and send you there within your own instance.
And you can do the same with usernames by using "@": @cile.sb@piefed.social
However, for linking someone a threaded comment specifically like Blaze just did? It's more awkward.
