With the current typehinting an IDE can't provide proper autocompletions for methods and other inspections.
class C1 {
protected \Drupal\node\NodeStorageInterface $nodeStorage;
public function m1() {
foreach ($this->nodeStorage->loadMultiple() as $node) {
$node->isPromoted();
}
}
}
The problem is that several method signature are defined in the EntityStorageInterface or ConfigEntityStorageInterface or ContentEntityStorageInterface.
The implementer classes use {@inheritdoc} for ::load() and for other methods as well.
That means an IDE still thinks that the return value of a NodeStorageInterface::load() is null|EntityInterface instead of null|NodeInterface
That is why an IDE can't provide more accurate help.
Add @method PhpDoc entries for every EntityStorageInterface descendants.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Postponing on #2920333: Allow PHPDoc @method annotations in class headers. → though there hasn't been movement on that in 5 years so not super promising.
