Yes. Client authors need to add an a tag when responding to a long-form note since we can't use the id to refer to it forever (it changes when the long form note is updated). Other than that I'm not doing anything special in habla.

Long-form notes are nip-33 parameterized replaceable events so I'm using the `a` tag to be able to comment (kind 1) and zap (nip 57) a long-form note. I want to be able to fetch comments and zaps for a post even after it has been updated so using its address (immutable) instead of event id (changes on every update).
Would be nice if "social" clients did that too.
