make-symbolic-link should not prevent you from creating to a link
to a file that doesn't exist.  Especially since you can pretty much
never tell whether the file will ever exist or not.

Maybe my point of view is too posix-centric, but I really would be
annoyed if eshell prevented me from creating symlinks just on the
basis that Emacs thinks the target is "invalid".  I use invalid
targets all the time (g.e. because the filesystem is currently
mounted at a different location than the "final" one, or because
I want to store non-filenames and have `ls -l' show me that data
or because I know that the data is small and that my filesystem
stores such data more efficiently if I use symlinks rather than
files, ...).
And I don't think my usage pattern is unique.
