Unless you go to some length with a dpkg path-exclude, but then that's a
bit more difficult to undo as uninstalling a package.  It's also trivial
to install the terminfo entry on the remote system $REMOTE:

infocmp screen.xterm-256color | ssh $REMOTE tic -

By their logic, adding entries to ncurses-base could also be harmful,
since they will likely not be available on remote systems for some time,
as servers tend to have older software than desktops.

Anyway, I'll add screen.xterm-256color to ncurses-base in the next
upload.  The ncurses-base package is badly outdated, it includes cruft
like xterm-r5 which nobody has been using for 15+ years but misses
terminfo entries which are popular today.

Cheers,
