Does not work over SSH

[rnwhitehead]

I'm building on an embedded system, using Visual Studio Code's remote build facility which works over SSH.
When I try to use dockerfile-plus I get the following:

=> [internal] load build definition from Dockerfile                                                                                                                                                                                          0.0s

I presume this is because it is trying to use the new fancy output format which won't work over SSH, is that correct?
