Where did you look? Wherever it was, it wasn't the right place, and is
giving bad information.
Several sites have published lists of ISO 639 language identifiers,
rather than simply providing a link to the official site. While this is
thought to be helpful, it is extremely unhelpful in that errors get
introduced or the information gets out of date. Anyone that has done
this is strongly advised to delete their private list and replace it
with a pointer to the official site:

No, it is not closed.

Part 2 was created in recognition that some applications require means
to identify more languages than 2Alpha can support, and require less
restrictive criteria for inclusion than are used in Part 1 (which was
created with terminology applications in mind).

While Part 2 was intended to be more inclusive than Part 1, it was not
intended to be comprehensive. (It was developed mainly with the needs of
libraries in mind.) Part 3 is intended to be comprehensive. The
relationship between the two is that they use a common 3Alpha identifier
space, and all of the items in ISO 639-2/T that are not collections are
also in ISO 639-3. A separate part (Part 5) which will have a complete
set of 3Alpha IDs for collections is also being developed. When it is
published, then parts 3 and 5 will cover the 3Alpha space, and Part 2
will be a profile of that combined space suited to some applications.
