Only use uv for some factors

[Cadair]

Hello,

I am interested in using uv for some factors and not others.

Initially, I tried to make the requires = line factor specific but that didn't seem to work, next I tried to do this:

runner =
    !oldestdeps: virtualenv
    oldestdeps: uv-venv-runner
package_tox_env_type =
    !oldestdeps: virtualenv-pep-517
    oldestdeps: uv-venv-pep-517

but that ends up throwing this error:

ROOT: HandledError| .pkg is already defined as a uv-venv-pep-517, cannot be virtualenv-pep-517 too

It seems that there's not a way to revert the overriding of the default by tox-uv which works? or am I missing something obvious?!

I totally agree with you, especially as I am sure that we will keep finding blocking bugs caused by either this plugin or uv itself, so having an escape route would be very useful.
