In general, it should not harm to have those extra packages installed and the required disk space should neither overwhelm a standard desktop or laptop.
Maybe you can make use of "/var/log/apt/history.log" to identify those packages [1]?
I have often thought Octave should have a "redistributable" that can be sent to people who don't need or want to run Octave but simply want to use an application that uses Octave.
This can be accomplished with Matlab by compiling the application code and sharing it (although accompanied by a fairly large redistributable runtime library I believe).
