It creates an extra process. On machines with more limited resources UUOC was discouraged, and still is, as a waste of system resources. An extension of that, creating way more child processes than need inside a loop is still a major performance issue.

Using anything unnecessarily should be discouraged, but to describe it as "useless" is overstating the mark.

It's not useless because it works. But it is unnecessary.
