Question around creating many streams for projects and scoping for security reasons

[drale2k]

HI @jorgemanrubia,

i watched the video and played with Turbo 8 refreshes. Working great for me but i have 2 questions i can't find an a proper answer to. Hope it's ok to open an issue for it as i am not sure where else to ask given the examples.

1. Creating a stream per project

In the demo app you are creating a separate stream per project:

<% @projects.each do |project| %>
  <%= turbo_stream_from project %>
<% end %>

Would this not create a lot of streams with a page of say 15-20 projects? Would love to know if this is a performance concern or not - as i would prefer it a lot over what i am doing currently:

Index.html.erb
turbo_stream_from [current_account, "projects"]

project.rb
after_update_commit { broadcast_replace_later_to [account, "projects"] }

I have 1 stream but have to scope it to current_account so only the project owner subscribes to the stream. Would appreciate your opinion this.

2. Scoping stream by passing an array to broadcasts_refreshes

I ended up with the above question because passing an array, to keep having a single stream with a string identifier, did not work for me in testing

broadcasts_refreshes [account, "projects"]

Is this an mistake on my side or is the idea with broadcasts_refreshes to subscribe to all items directly and not need to scope a stream for security reasons, like in the case above?
