Enable environment variable usage in triggers

[Laskewitz]

I would love to be able to use environment variables in triggers. For instance when using a SharePoint trigger, I would like to be able to use an environment variable for a site URL and/or a list name.

Agreed. Since the point of environment variables is to support proper ALM practices across environments, being able to point a trigger to respective dev/test/prod source systems is really important. For example, If my trigger is email arriving in a mailbox, I want to develop and test with dev/test mailboxes, without manually changing the Flow in different environments.
