Hi, can we instead add a new flag -c / --constraint to uv add, so that you can pass in constraint files directly? I think currently you can do this by adding a constraint to a requirements.txt file, then running uv add --requirements requirements.txt, but this would embed it directly in the command.

My specific use case is using Apache Airflow which only supports pip (not Poetry etc) because it basically requires constraint files, see https://github.com/apache/airflow/blob/main/README.md#installing-from-pypi

That way, I can do (copying from their example):

uv add 'apache-airflow==2.10.0' \
 --constraint "https://raw.githubusercontent.com/apache/airflow/constraints-2.10.0/constraints-3.8.txt"

Thanks.
