Continuation of https://github.com/neovim/neovim/pull/15202 A plugin like telescope could override it with a fancy implementation and then users would get the telescope-ui within each plugin that utilizes the vim.ui.select function. There are some plugins which override the `textDocument/codeAction` handler solely to provide a different UI. With custom client commands and soon codeAction resolve support, it becomes more difficult to implement the handler right - so having a dedicated way to override the picking function will be useful.
