Tasks to deprecate Migrate Drupal UI

What needs to happen to the css in stable 9, item 1 of the remaining tasks.

The CSS in stable9 can be removed in when this module is removed from core. The same happened for tour 📌 Remove Tour module Fixed

Is there any else to do here?

The last file is that needed? To install path_alias?

That test installs path_alias in a kernel test but does not install the entity schema which Migrate Drupal UI seems to need but doesn't have a dependency on.

NW for a code comment. (See my long-winded explanation on the MR.)

I am adding the tag for a followup (also in my MR comment). I will create the followup issue unless you do it first.

@benjifisher, thanks for the details of why the entity schema is needed. I admit my earlier reply lacked detail and could be seen as, well not kind. It is a reminder to take more care after a disturbed night of sleep.

I've copied the comment. And that too I should have looked for in the issue.

Linting has passed so setting this to NR.

The Needs Review Queue Bot → tested this issue. It no longer applies to Drupal core. Therefore, this issue status is now "Needs work".

This does not mean that the patch necessarily needs to be re-rolled or the MR rebased. Read the Issue Summary, the issue tags and the latest discussion here to determine what needs to be done.

Consult the Drupal Contributor Guide → to find step-by-step guides for working with issues.
