Not compatible with what?

I primarily wanted to define the mode hook as a variable so that I
could give it docstring.  I chose defcustom over defvar because
define-minor-mode and quite some other major modes did that.  I don't
strongly object to making the defcustom a defvar, but I don't
understand your problems with the use of defcustom:

I don't recall the bugs you refer to; could you give me the subject(s)
of the relevant thread(s)?
