Option to disable linehaul

[eaubin]

https://github.com/astral-sh/uv/pull/2493 added linehaul metadata to the uv user-agent string. For example,

• Windows GHA: uv/0.1.21 {"installer":{"name":"uv","version":"0.1.21"},"python":"3.12.2","implementation":{"name":"CPython","version":"3.12.2"},"distro":null,"system":{"name":"Windows","release":"2022Server"},"cpu":"AMD64","openssl_version":null,"setuptools_version":null,"rustc_version":null,"ci":true}

I'd like to use uv at work, but this is causing my network admins some grief. Could an option to disable the linehaul metadata be added?

Do you know if pip includes an opt-out for this? (just wondering)

[eaubin]

I believe that's controlled through $PIP_USER_AGENT_USER_DATA

I think that's additive; it doesn't look like it disables linehaul.

iirc pip doesn't allow opt-out either, it's standard telemetry pypi expects

My network admins loosened their rules, so its not a requirement for my org anymore. I still think its a good idea to allow opt out (or better yet opt in), but since it's very low priority I'll close the issue.
