should action compressors create artificial actions?

[sgratzl]

in the current version action compression can only remove actions from the execution chain. However, sometimes it might be useful to add a replacement action for it. However, this temporary action won't be part of the real provenance graph.

simple example:

assume a simple calc app. i.e. all operations on the current number are tracked (+3, -2, +4). An action compressor could replace the previous chain with a single artificial command: +5.
