Service offering changesets with their respective old objects

i was thinking about analysing changeset changes and one of these issues is always at the start of that pipeline that changesets only contain the new or then current versioned e.g. changed objects. So one always starts with fetching ALL the version-1 objects in that changeset. This is pretty resource hungry and time consuming which makes stuff like OSMCha slow.

Is there any service offering the changesets as seperate objects including their respective old object versions?

I guess that would be fantastic one-stop-shop for all these “lets analyse changesets live” ideas not in the situation to set up a full planet postgis database to quickly fetch version-1 objects.
