I guess there are two things to say about this:
1) not everybody wants /etc/shells, and having screen (or any other
recipe) create that file unilaterally seems like a bad thing.
Especially since there doesn't seem to be any corresponding postrm to
clear it up if screen is then removed again, nor is /etc/shells
mentioned in CONFFILES.
2) even if you did want to create /etc/shells, the touch is unnecessary
because "echo foo >> FILE" is perfectly capable of creating the FILE if
it didn't already exist.
