foo f;

This f is not shared between threads, even though the
__gshared indicates it should be. Why is this not an error?

You need to use __gshared with the instance instead:
__gshared foo f;

Hence my asking 'Why is this not an error?'.

However, shared struct foo {} works, so one might
expect symmetry to dictate that __gshared might, too.

Because DMD ignores invalid attributes, and almost never flags them as an 
error (or even a warning!).

`shared scope immutable import foo;`

FWIW, I disagree with this behaviour -- SDC[1] will warn on no-op 
attributes.
