Question regarding Canary

[Kent Fredric]

I'm just asking for some clarity with regards to the use of the
Stability Canary.

I have no personal intent on using it, I'm just seeing its use in a
few places and I don't fully grok the intent.

For instance, inside the recent change to Linux-DVB, this was added:

   use Canary::Stability Coro => 1, 5.006;

What does this mean semantically?

My understanding is that statement warns that Coro will not work on some Perls.

But what relevance does this have to Linux-DVB?

I'm missing some data in my understanding as to why Linux-DVB cares
that Coro may not work, as my expectation is that problem would be
handled in Coro.

Thanks.
