replies always notify the parent, even if no handle is included
this is different from the mastodon behavior although not necessarily a bug but i didn't see an issue open so im opening this one
here's an example.... the reply notified the OP https://anticapitalist.party/@cosine/101186155101054809
the advantage of doing it based on handles is more control.... i can add a reply to do a "LB" sort of thing without notifying the OP
also, in a DM thread (which this works for too) its important to be able to easily see and control the recipients
