Inconsistent return type for getStoreId()

[sreichel]

Summary

• Magento 2.*
• PHP7.1
• using strict type decalaration

getStoreId() returns a string for products, but int for categories that causes a fatal error in extensions code.

Examples

Simplified code:

ObserverA:

https://github.com/magento/magento2/blob/2.3-develop/app/code/Magento/Catalog/Model/Product.php#L521-L532

$product = $observer->getProduct();
$storeId = $product->getStoreId();
$result = $this->someMethod($storeId);

ObserverB:

https://github.com/magento/magento2/blob/2.3-develop/app/code/Magento/Catalog/Model/Category.php#L560-L573

$category = $observer->getCategory();
$storeId = $category->getStoreId();
$result = $this->someMethod($storeId);

Shared method

public funtion someMethod(int $storeId)

If i pass products store ID to someMethod i get a fatal error.

Proposed solution

1. cast return type to int in product model
2. check all (80) getStoreId() methods to return always int value

Would create PR for "1." since I#ve not enough time to check all others.

Please advice.
