Describe the solution you'd like
These taxa should be removed for all analyses, 16S and shotgun. This may require a custom script. Qiime2's qiime taxa filter command is basically broken, we can't be certain that just plugging these taxa into that command would have the desired effect.

Describe alternatives you've considered
We've mentioned decontam #412 in the past, could it help somehow? Are there other decontaminating tools available to us?
