Personally, I think quite the opposite: named constructors make a lot
more sense than type-based overloads. For instance, you might have both
createFromJson and createFromYaml; their inputs are both going to be
"string" as far as the type system is concerned, so overloading would
be useless.
To add an example from PHP’s standard library: The new DOM API shipped
in PHP 8.4 uses named constructors to create documents and requires this
to distinguish between `createFromFile` and `createFromString`.

final class HTMLDocument extends Document
{
public static function createEmpty(string $encoding = "UTF-8"):
HTMLDocument {}
public static function createFromFile(string $path, int $options
= 0, ?string $overrideEncoding = null): HTMLDocument {}
public static function createFromString(string $source, int
$options = 0, ?string $overrideEncoding = null): HTMLDocument {}
// […]
