[infinispan-dev] Write-only commands

Hi, I am working on entry version history (again). In Como we've discussed that previous values are needed for (continuous) query and reliable listeners, so I wonder what should we do with functional write-only commands. These are different to commands with flags, because flags (other than ignore return value) are expected to break something. I see the available options as: 1) run write-only commands 'optimized', ignoring any querying and such (warn user that he will break it) 2) run write-only without any optimization, rendering them useless 3) detect when querying is set up (ignoring listeners and maybe other stuff that could get broken) 4) remove write-only commands completely (and probably functional listeners as well because these will lose their purpose) Right now I am inclined towards 4). There could be some internal use (e.g. multimaps) that could use 1) which is ran without a fancy setup, though, but it's asking for trouble. WDYT?
