nextest creates an empty target/nextest/default directory even when CARGO_TARGET_DIR is set

[sampathsris]

This is my setup:

$ cargo nextest --version
cargo-nextest 0.9.103 (d2e7b879f 2025-08-25)
release: 0.9.103
commit-hash: d2e7b879fb79975e8b47a8e3ce569b651e6381c0
commit-date: 2025-08-25
host: x86_64-unknown-linux-gnu

$ env | grep TARGET
CARGO_TARGET_DIR=/home/sampathsris/.cargo/build/

Whenever I run cargo nextest run, an empty target/nextest/default directory gets created. It just a minor annoyance, but I'd still like to avoid that. Is there a way to do it?

Or should I report this as a (cosmetic) defect?

See #2154 for some initial work. Looking for someone to pick it up and complete it -- would you like to?
