Yes, it's still the case that only chats can be popped out and not channels.
I guess channels and chats differ by exclusivity and recency. Chats auto-sort by latest and are invite-only; a Team can be a "public square" for petitions or callouts.
There are use-cases for private Teams if additional features beyond chat are needed.
Channels require scrolling, so it's usually easier to ping someone instead. Channels as webhook sinks incentivize regular checking, but only if the user is actively seeking.
