Why do you think these were accidentally added? These look like the chr20 subsetted files that @koncheto-broad uses for his slimmed down quickstart. Might actually be good for a quick testing framework some day. Or I could be completely off base!

Nah, this wasn't me. It looks like files that Rori added a while ago.

Why do you think these were accidentally added?

To be more specific I think the files were not accidentally added, but multiple copies of these files were added in the 050ef8a commit in May of 2020 and I think the paths I'm removing here were not the intended paths. Copies of these files were added at the root of the GATK repo, under NA12878, and under src/test/resources/org/broadinstitute/hellbender/tools/walkers/variantutils/ReblockGVCF/NA12878. I'm planning to keep the copies at that last path and move those files to the new repo.

Thanks for the context! I do like a good PR that deletes things.
