Alexa Configuration is Exclude Default?

I’ve been looking through the threads here and can’t determine the default behavior of the Alexa integration. Can someone tell me, before I pull the trigger, does it automatically exclude everything by default and then you just build it in configuration with including entities and domains?

The Alexa itself is so limited once things get into it, you either have to forget one by one or forget all and potentially lose your routines in it. I’d rather not have 80+ things suddenly appear in it!

the filter is not greedy. Add entities as you wish.
