Mainly because it's a convenient list of "real" shells, and some of the
remote service applications require a shell to be in that list. FTP is
one such that springs to mind. As a counter example, /bin/false is a
possible shell but it doesn't provide a particularly useful environment
for the user. You could change the scriptlet to check for the 7th column
being either empty or an executable file if you preferred.

I don't recall the OP mentioning access via sudo. (BICBW.)

ForceCommand requires an interactive shell-like login on the target,
so I don't believe that's relevant here.
