Problem/Motivation
Goutte itself is deprecated and is just an alias to Symfony\Component\BrowserKit\HttpBrowser. However, Drupal depends on behat/mink-goutte-driver which of course depends on Goutte. However it does not seem like we quite depend on the particulars of the very minor features implemented in behat/mink-goutte-driver on top of Goutte (AKA Symfony\Component\BrowserKit\HttpBrowser).
Proposed resolution
Swap out using Goutte itself with Symfony\Component\BrowserKit\HttpBrowser and behat/mink-goutte-driver with its existing underlying dependency behat/mink-browserkit-driver.
Remaining tasks
Figure out what we need to change.
Replace behat/mink-goutte-driver with behat/mink-browserkit-driver as a dependency.
