Yes, we've been talking about this for a long time. And tye has been planning on doing it for a long time. But he's got a huge list of other shortcut enhancements, and I guess he wants to roll them all out at the same time.

See e.g. Re: Problem with id:// shortcuts and anchors (care).

Btw - some shortcut types do already support linking to named anchors; just not all of them; and not [mod://].
