Please explain what usecase is covered by this change?

https://github.com/cycle/orm/blob/master/src/Factory.php#L177 Scopes were attached by default at source level - so all repositories were reading them correctly. Select was created without a scope on purpose.

I thought this more clear way to define scope on any loader, not just joinable. May be I get it wrong, but what is the purpose to not attach scope to select?
