Conflicting intellisense suggestions

Describe the bug There's this weird case, when you set workspace to limit to a particular PHP version, and use a feature, which is described in validator with a syntax unsuitable for such version.

To Reproduce A simple example could be created by using Countable interface with codebase restricted below v7.

/** Use PHP=^5.6 */
class TestClass implements \Countable {
  public function count() {
    return 0;
  }
}

which produces an error explaining that the method does not match interface definition.

Method 'TestClass::count()' is not compatible with method 'Countable::count()'.intelephense(P1038)

TestClass::count

Count elements of an object

<?php
public function count(): int { }
@return int<0, \max> The custom count as an integer.

An attempt to "fix" definition instantly switches the warning to say that "7.0+ syntax is used where limit is ^5.6".

Expected behavior Indeed, the expected behavior to "just work". I would suggest validating the builtin definitions before spoiling them and suppress errors that would indicate version mismatch, if applied.
