Developing Extension Pack is harder than this patch. (it means, that
only very big features will make it into ext.pack), or features with
incompatible licenses (like VNC).

Just don't use it if you don't like it. I don't use "Host-only
network", because for my use cases, loopback + bridge cover this need.
UDP tunnel is not secured, and this is by design, and documented in the docs.
