In automation scenarios where access to the filesystem isn't possible, as is typically the case for ephemeral CIs, there isn't any reason to make copies of the project. This copying causes a problem for larger projects when the disk space on runners is limited.

For example: https://github.com/gradle/develocity-oss-projects/actions/runs/10027093868

This can also be a problem for any sized project running on non-ephemeral CIs that do not regularly clean up the disk as it will just continue to grow over time. This non-ephemeral CI case could also be fixed by #640.
