Comment 4 for bug 1786966

My 2 centimes:

Removing a widely used binary that's been around for decades as part of a bugfix release, without warning or prior announcement, is rude and completely out of question.

For now (i.e. 7.0.2), I would support printing a deprecation warning on the console and into the log when starting iocLogserver.
A minor release (7.1) could have iocLogServer as a script that calls a plug-in-compatible replacement.
Complete removal will have to wait for a major release.

Such a change (iocLogserver -> logstash) requires *major* changes for packaged versions of Base and any productional systems.
