I believe that the changeset that you reverted was an attempt to create "boundary=disputed" areas such as https://www.openstreetmap.org/relation/17296617, in line with what is written at https://osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf "We have and will continue to build mechanisms
where alternatives can be recorded and easily used in maps more suitable to you".
You reverted it without any discussion, which isn't OK.
I do notice that some of the objects here at admin_level=4 and below are boundary=administrative objects.  That isn't unusual in OSM; countries often claim to "administer" areas that they don't control but only pretend that they do.
Please discuss your problems with https://www.openstreetmap.org/changeset/148136531 et al with the author of that changeset in a civilised manner?
I'd actually suggest that https://community.openstreetmap.org/ is the best place to do that.
