Bug? Add-PnPContentTypesFromContentTypeHub doesn't work in Private or Shared Channel Sites

[sparkitect]

This command fails if the Content Type includes a Managed Metadata column AND the site is a Channel site (Private or Shared):

I believe this is because the activation of the hidden "TaxonomyFieldAdded" Feature has been skipped in the interest of fast creation of the site.

The work-around is to run the following command prior to this one:
Enable-PnPFeature -Identity 73ef14b1-13a9-416b-a9b5-ececa2b0604c -Scope Site -Force

I believe this to be a bug that exists at a lower level than PnP, so changing the Add-PnPContentTypesFromContentTypeHub command so that it activates the Feature for us seems silly.

Here's a screencast of me speedrunning the bug and work-around: https://youtu.be/_Ty_hXOGhOY

UPDATE: This also seems to be an issue w/ Shared Channel sites - title and content edited to reflect.
