This is what happened with the Language Server Protocol.
Prior to 0.9 (if I recall correctly), you had to install a plugin to be able to interface with LSP servers, and in 0.9 they integrated the support into NeoVim itself.
Would be nice to also have such support for DAP, though nvim-dap is doing a good job so far.
