802.1Q != CCNA..
Look at the spec, Table 9-2 on page 86. (100 in PDF)
VID Use
0 "no VLAN identifier is present in the frame"
1 "The default PVID value used for classifying frames on ingress ..
The PVID value of a Port can be changed by management."
FFF "Reserved for implementation use."

Any VID can be untagged. While 1 is the default it can change and
OpenVPN shouldn't really care.
One alternative approach to using tag 0 would be to introduce a
vlan-pvid (or vlan-default-tag) option to set the PVID.
But explicitly allowing tag 0 can also be useful.
