IMNSHO, not explicitly enough:

  ** Emacs now supports being built with pure GTK.
  To use this option, make sure the GTK 3 and Cairo development files
  are installed, and configure Emacs with the option '--with-pgtk'.
  Unlike the default X and GTK build, the resulting Emacs binary will
  work on any underlying window system supported by GDK, such as
  Wayland and Broadway.

No matter how many times I re-read this, I fail to understand that it
tells me not to use it on X, and it definitely doesn't warn me of any
downsides if I do.  A word of warning is definitely in order there.
