supressed memory limit error at imagecreatefromstring

[klugmario]

Hello,
I just found out that a fatal error thrown by imagecreatefromstring in wp-includes/class-wp-image-editor-gd.php gets suppressed by an @ before the function call.
​https://github.com/WordPress/WordPress/blob/master/wp-includes/class-wp-image-editor-gd.php#L97

Is this really neccessary?
I had to dig very deep to find out why a clients homepage on a hosted environment does not work.
Without this the out of memory limit error message would have been displayed by enabling WP_DEBUG.

For my understanding it would not make mp difference without the @ when WP_DEBUG is not enabled.

Why it's not possible to increase the limit with ini_set or .htaccess is a topic for the hoster but it would have been fine to see this error.

Thanks in advance.
