@mfreed7 @josepharhar can you help me review this? It was unusually difficult to discern which tests are for which feature, with tests found in a lot of different directories, for different features. Here are all of the files not mapped here that have the word "commandfor" in them:

html/semantics/interactive-elements/the-details-element/details-toggle-source.html
html/semantics/interactive-elements/the-dialog-element/dialog-toggle-source.html
html/semantics/menu/tentative/button-invoke-menulist.html
html/semantics/menu/tentative/focus-menu-elements-arrowoperations.html
html/semantics/menu/tentative/focus-menu-elements-nested-arrowoperations.html
html/semantics/menu/tentative/menubar-invoke-menulist.html
html/semantics/menu/tentative/menuitem-activate.html
html/semantics/popovers/popover-focus-2.html
html/semantics/popovers/popover-focus-3.html
html/semantics/popovers/popover-focus-4.html
html/semantics/popovers/popover-light-dismiss-command.html
html/semantics/popovers/popover-toggle-source.html
html/semantics/popovers/popovertarget-disabled-fieldset.html
shadow-dom/focus-navigation/menu/tentative/focus-menu-elements.html
shadow-dom/reference-target/tentative/commandfor.html
shadow-dom/reference-target/tentative/resources/property-reflection-helper.js

Should anything in this list be considered tests primarily for command/commandfor?

html/semantics/popovers/popovertarget-disabled-fieldset.html seems closely related enough to commandfor that I'd include it.

html/semantics/popovers/popover-light-dismiss-command.html seems like a copy of popover-light-dismiss.html which uses command attributes instead of popovertarget. I'm not sure why it was created, but it primarily tests light dismiss. I'm not sure if it should be considered part of command/commandfor or not.

The rest of the tests I'm pretty sure are not primarily for command/commandfor.

+1 to all of this. I think it's just that command is so useful that it gets used as a "feature" in other tests, to test other things. That plus several new features (e.g. reference target and menu) need to consider command.
