If it's disabled, it doesn't belong in the terminal description.
(a terminal description is a collection of features for a particular
configuration, including commonly-used features such as cursor-visibility
that can be altered using -- you guessed it -- the terminal description)

again, disabled by default makes it not part of the terminal description

then you've invented your own default which doesn't match the DEC terminal

ncurses does this (tic's got a warning pointing out that some applications
don't work with that combination, but as I recall it, that's vi from about
30 years ago)
