I understand that used to be the case. However, at z/OS 1.7:
12.19 "z/OS V1R7.0 MVS JCL Reference"

I had thought this change was made somewhat earlier, but I
see revision bars at the 1.7 level.
This doesn't say that the ENQ of a statically allocated data set
will be released any sooner if the programmer codes FREE=CLOSE.
