For root table, I thought the previous problems about meta table will become
the problems about root table. root table should be splitable? If root table
cannot splitable, which regionserver to host root table's region, a isolated
region or share with user regions? In our production use case (300+
RegionServer, 200K+ Regions, 1K+ tables), the meta region is isolated on one
regionserver, not share with the user regions. This is a waste of machine, but
for better stability. And we have many hack logic for meta regions, such as
assign meta first, donot replicate meta wal, balancer give a bigger weight for
meta region, the new root table need all these hack, too? You can found these
by grep isMetaTable or isMetaRegion calls in our codebase...

Have you tried regionserver groups? In our deploy we isolated it by having a
system regionserver group which hosts all the system tables (root, meta, etc).
