Summary

In PR #16528, the ability to exclude dependencies when installing a python package was added.

This functionality can be used when installing a tool, like so:

$ cat /tmp/excludes.txt
markdown-it-py

$ uv tool install --excludes /tmp/excludes.txt 2048-cli==1.0.2
Resolved 7 packages in 11ms
Installed 7 packages in 35ms
 + 2048-cli==1.0.2
 + click==8.3.1
 + maturin==1.12.0
 + numpy==2.4.2
 + pygments==2.19.2
 + rich==13.9.4
 + rich-menu==0.3.0
Installed 1 executable: 2048-cli

If the --excludes option was omitted from the previous command, we would see markdown-it-py==4.0.0 installed by uv.

If we then upgrade this tool, we will see our excluded dependency is reinstalled:

$ uv tool upgrade 2048-cli
Updated 2048-cli v1.0.2 -> v1.0.3
 - 2048-cli==1.0.2
 + 2048-cli==1.0.3
 + markdown-it-py==4.0.0
 + mdurl==0.1.2
Installed 1 executable: 2048-cli

Since the uv tool upgrade command does not accept the --excludes cli arg, I would expect that the correct behaviour on upgrade is to exclude the same dependencies as when the tool was first installed.
