Using --cquery can't skip targets

[BbBaboo42]

In our repo, we use analysis tests from rules testing (https://github.com/bazelbuild/rules_testing)
We have custom tests, and to in order to test them, we create a target that should fail and pass to an analysis_test.
Right now we use query, which is fine, because it doesn't the _impl functions don't run in query.
On the other hand, in cquery, the _impl functions do run for all the targets in the repository.
the main we need the option to prevent the cquery from running on those targets.
There are a few possible solutions we think might help us:

• allow to pass the cquery as input instead of the fixed "deps(//...:all_targets")
• when cquery runs on a target that fails, ignore it.
