Description
With a pixi.toml like this,
[workspace]

python = "python"
[dependencies]
python = ">=3.14.1,<3.15"I get the following results if I run it on my linux-64 machine:

WARN Not installing dependency for (default) on current platform: (linux-64) as it is not part of this project's supported platforms.
✔ The default environment has been installed.
You can see that it let's me proceed in both cases, in the first case simply using my global Python without any warning.
I would expect that it fails in both cases, since my platform is not part of the supported platforms of the default environment
