[PP-1] TaxonomyFormatterBase should extend EntityReferenceFormatterBase

I'd suggest we should wait for #1847596: Remove Taxonomy term reference field in favor of Entity reference.

#2405469: FileFormatterBase should extend EntityReferenceFormatterBase is in, so unpostponing… but I think this is now actually still postponed on #1847596: Remove Taxonomy term reference field in favor of Entity reference?

And this would greatly simplify #2099137: Entity/field access and node grants not taken into account with core cache contexts.

This is actually postponed on #1847596: Remove Taxonomy term reference field in favor of Entity reference, which is postponed on two independent chains of issues:

1. #2446613: Fix MigrateVocabularyFieldTest
2. #2446511: Add a "preconfigured field options" concept in Field UI which is blocked on #2373491: Categorize field type plugins

#2373491: Categorize field type plugins is in.

#2446613: Fix MigrateVocabularyFieldTest was closed as a duplicate. So now down again.

#6 referred to #2099137: Entity/field access and node grants not taken into account with core cache contexts, not #1847596: Remove Taxonomy term reference field in favor of Entity reference. Fixed that.

#2446511: Add a "preconfigured field options" concept in Field UI landed.

Now only blocked on #1847596: Remove Taxonomy term reference field in favor of Entity reference.

Actually, it seems like this should be closed as a duplicate when that lands, no? :)

I was actually going to ask you exactly that. I didn't realize the other patch included the formatter changes. I guess the formatter changes must happen in that issue, right?

There are no changes needed AFAIS, that issue simply removes TaxonomyFormatterBase in favor of EntityReferenceFormatterBase.

Okay, marking this is a duplicate :)
