Legacy Script Plugin in vSphere Client 6.7

Hi!  We have a legacy script plugin which works fine in 6.0/6.5 with scriptPlugin.enable=true in webclient.properties.

However, the plugin doesn't show up in 6.7 (both vsphere-client and vsphere-ui clients), and there is no error messages in vsphere_client_virgo.log.

Can anyone from VMware confirm if the legacy script plugin still works in 6.7?

Thanks a lot,
