Have Draytek effectively ceased to be interested in supporting OpenVPN?

It was a feature of the older firmwares, but now not much support (current firmwares seem to have no OpenVPN) ... which is disappointing, and a bit annoying when making a decision about a platform/provider/solution ... can we get a firm steer on whether this is just a development stage or a decision to drop support?

It was never part of the formal specification but was tested briefly and as I understand it has not been implemented across the range with no further support planned. You can use SSL VPN and IPSec as previously.
