Does 11.5.2 include Bug Fixes from any 11.5.0 and 11.5.1 Hotfixes?

It looks to me, from existing documentation, that 11.5.2 should notionally be a different release, even though it might just incorporate those hotfixes only. It is a necessary release because 11.5.1 alone causes stability issues for anyone upgrading from a previous release to 11.5.1.
