I wouldn't expect it to be "quite low", but I build them regularly,
and so do most of the people I work with. On unix systems, the
predominate way to plug to programs together is still via the standard
IO pipes, which the programs - even if normally invoked from some
visual tool - can be used from the command line. And many of us work
develop on one system, then deploy on something else via SSH, so being
able to deal with things on the command line - even if it also
provides some kind of GUI - is a useful feature.
Admittedly, JVM languages don't lend themselves to such things, what
with having to either start it on every command or have some kind of
server running to avoid that.

This sounds more like an issue with those "commonly recommended ways"
than with clojure or it's REPL, since it works fine running from a
shell.
