Why is 32768-60999 the default for local/ephemeral ports?

The local port range on my Arch Linux installation is 32768-60999 according to
cat /proc/sys/net/ipv4/ip_local_port_range
[Wikipedia](https://en.wikipedia.org/wiki/Ephemeral_port#Range) states that this range is "used by many Linux kernels" and [the kernel documentation](https://www.kernel.org/doc/html/latest//networking/ip-sysctl.html#ip-variables) says it's the default range.
~~I'm especially interested in the reason for exluding ports 61000 to 65535 from use as local/ephemeral ports per default.~~
