Yes, we can disable it. It's mostly an incomplete experiment at seeing whether we could get rid of the NodeStoreBranch feature entirely by pushing the existing RootImpl purge logic down below the NodeBuilder interface. Another rationale was to see how far we could go without having to rely on branches, as the MongoMK didn't yet support that feature. I intentionally set the update limit high enough so that the functionality is only triggered in custom test cases and in normal use the much lower purge limit in RootImpl takes care of branch handling.
