Conflicting instructions for installing nvim-orgmode

[wolfv6]

I installed nvim-orgmode on LazyVim using the instructions on
https://github.com/nvim-orgmode/orgmode#installation > lazy.nvim (recommended)
It uses:

  event = 'VeryLazy',
  ft = { 'org' },

The instructions on https://nvim-orgmode.github.io/installation.html say:
Lazy loading (Not recommended)
Lazy loading via ft option works, but not completely. Global mappings are not set because plugin is not initialized on startup.

What are the consequences of not setting global mappings in nvim-orgmode?
Can it cause loss of functionality?
Does "Global mappings" refer to key mappings?
