We feel like our migration experience is quite good right now and we don’t plan on doing custom rules and filters for now.
Some of those can already be done using PowerShell, SharePoint views and other means.
We will eventually reevaluate this once we advance further in our roadmap.

It's nice that you feel like your migration experience is quite good right now, but many people have asked for this feature. I understand it's a big change to add it to the UI, so how about adding it to PowerShell? I've tried migrating a specified set of lists as a substitute for excluding lists, but we have a lot of lookup columns, and this rapidly becomes too complex to be workable.
