[4.0.0-beta.1] Replacements for 'cp.entries.edit.details' hook and draftEditor.on('createProvisionalDraft') js event

Description

Not really a bug, but maybe some missing info in the upgrade guides.

Upgrading plugins/modules went very smoothly so far, just one thing i couldn't figure out in entries edit pages:

In 3.7, we are adding custom buttons to the end of the sidebar via the now removed hook cp.entries.edit.details.

Could only find the Element::EVENT_DEFINE_SIDEBAR_HTML event, which places the added html somewhere in the middle of the sidebar. Is there a possibility/event to add the html to the very end of the sidebar?

The compare button is hidden by default in 'Current' entries, and gets enabled when a provisional draft is created:

window.draftEditor.on('createProvisionalDraft', function() {
    newDraftId = window.draftEditor.settings.draftId
    ...
     $('#draft-new').css('display', '')
});

This obviously does not work anymore, is there another js event we could hook into that gets fired when a provisional draft is created and contains the new draftId?

(If not, this is a FR :-)
