Question

For multiple platforms I know I can do something like

foo = [
    { version = "^1.0.0", platform = "a" },
    { version = "^1.0.0", platform = "b" }
]

But how can I specify != instead of == that Poetry uses? It's not feasible to manually write out all other platform besides the ones I want to ignore and the syntax above is cumbersome enough as is.

Specifying arbitrary environment markers, including negative ones, is supported in the 1.0.0 latest prerelease (see #1142). You can start using the prereleases is you want to have this feature
