Is there any way to “subscribe” to stream deletion? I can track stream creation by subscribing to $streams (or $category-x) stream, but is there something symmetrical for deletion?

Sorry, there isn’t a way to do that. What’s the use case, perhaps there’s another way to approach this?
(Adapted to public) use case is something like that: I have a document
that in its lifetime is categorized by several so-called traits. Every
categorization is an event in document stream, and I back-reference
document from trait stream via subscription (e.g. on each
categorization event in document stream a "documentAdded" event is
emitted to trait stream). When the document is deleted (and due to
compliance reasons it's deleted entirely, with its stream), I want to
delete all the references to it from trait stream.
Of course I can firstly emit a "delete" event to document stream, and
then, from subscription, delete the stream itself, but that seems...
awkward.

This is actually the best way of doing it as we internally have no idea where your consumers may be (think 10k messages behind then we delete the stream)
