Sort of random question - in the Guide, as it demonstrates extending the Stack construct, is appears that each stack module instantiation from index.js includes an "id" property in props i.e "auth", "api", etc. but inside the stack definition, rather than use that passed id property, it is hardcoded again in the individual SST calls i.e. this.api = new sst.Api(this, "api", {}) and this.auth = new sst.Auth(this, "auth", {}) Is there a reason that the id property isn't used? Am I missing a convention or something?

Might be better to ask this over on #help or #sst!
