Deprecate random_string basic/md5/sha1

Is anyone using the following types of random_string()?

basic: A random number based on mt_rand() (length ignored).
md5: An encrypted random number based on md5() (fixed length of 32).
sha1: An encrypted random number based on sha1() (fixed length of 40).

As you know, these values are cryptographically insecure.
I personally do not understand the use case.
I suggest that they be deprecated.
