### What should this feature add?

By placing the cache in the Windows user profile by default, you're eating space that the user might not afford. C Drives on modern PCs are often small SSD or M2 drives. Besides that, by forcing the cache to C, you're creating this issue:

**warning: Failed to hardlink files; falling back to full copy. This may lead to degraded performance.
If the cache and target directories are on different filesystems, hardlinking may not be supported.
If this is intentional, set `export UV_LINK_MODE=copy` or use `--link-mode=copy` to suppress this warning.**

Please allow us choices for file placement. You don't know our space constraints.

**DON'T BE ANOTHER MICROSOFT.**

### Alternatives

There's no workaround. You decided where to put the cache, not me
