What sort of security implications did you have in mind? Just curious.
I think the common uses of VLANs are to segregate traffic to reduce collisions, and to segment networks for security. If you've added VLAN 1 as the native VLAN, you might be exposing this host to attacks from that VLAN (assuming you gave it an address), or you might be exposing other hosts on the VLAN to attacks from that host if it's compromised. If your security policy is based on the policy of least privilege, then it's best not to provide a host with VLANs that it doesn't use/need.
