    How to execute logic when NavigationLink is tapped?

FB10144005

Currently it doesn't seem possible to execute additional logic when a navigation link is tapped with the new NavigationLink(value:) initializer. When the link is tapped it updates path state all the way back at the root NavigationStack to drive navigation, but there are many times where we need to perform logic after the tap and before the drill down.
For example, after tapping a link we may want to pre-emptively load some data to show on the drill down screen. Or we may want to perform some form validation. Or we may want to track some analytics. This does not seem possible with the current link API.
A workaround is to use Buttons instead of NavigationLinks, but then you lose all of the styling and affordances given to links, such as chevrons when used in List.
If the API for NavigationLink cannot be changed to accomodate for this, perhaps a new ButtonStyle could be introduced that allows regular buttons to take on the sty
