Using drupal-core-strict for PHP >=5.5.9 compatibility

I've been using drupal-core-strict to be able to install and update Drupal using Composer on a server with PHP 5.6. Until now it has worked fine, but now (with Drupal 8.4.4) I get the following:

  Problem 1
    - Installation request for symfony/cache v4.0.4 -> satisfiable by symfony/cache[v4.0.4].
    - symfony/cache v4.0.4 requires php ^7.1.3 -> your PHP version (5.6.33) does not satisfy that requirement.
  Problem 2
    - Installation request for symfony/var-dumper v4.0.4 -> satisfiable by symfony/var-dumper[v4.0.4].
    - symfony/var-dumper v4.0.4 requires php ^7.1.3 -> your PHP version (5.6.33) does not satisfy that requirement.
  Problem 3
    - Installation request for doctrine/instantiator 1.1.0 -> satisfiable by doctrine/instantiator[1.1.0].
    - doctrine/instantiator 1.1.0 requires php ^7.1 -> your PHP version (5.6.33) does not satisfy that requirement.
  Problem 4
    - doctrine/instantiator 1.1.0 requires php ^7.1 -> your PHP version (5.6.33) does not satisfy that requirement.
    - phpspec/prophecy 1.7.4 requires doctrine/instantiator ^1.0.2 -> satisfiable by doctrine/instantiator[1.1.0].
    - Installation request for phpspec/prophecy 1.7.4 -> satisfiable by phpspec/prophecy[1.7.4].

If using drupal-core-strict results in getting exactly the versions of Drupal core's dependencies as they are specified in Drupal core's composer.lock file, I'm not sure how this is possible? Is this an issue with drupal-core-strict or am I mistaken in my assumption that Drupal 8 is compatible with PHP >=5.5.9? What would be the best way to ensure PHP >=5.5.9 compatibility with Composer installs?

symfony/cache is not a core dependency afaik. Could you run "composer why symfony/cache" to see which package requires it?

Thanks for your quick response! Indeed, it looks like Drupal Console's requirements are causing this.
