I did try. Only ~40% of defcustoms are supplied with :version tags.
Also, ~75% of the tags were introduced long time ago: Emacs 24.
The rest, except the 4 (four in total) Emacs 27 are all Emacs 26.

Sure. Just trying to clarify my confusion. The inconsistency with some
defcustoms using :version and some not is bugging me.

Best,
