The latest SIM v1.5.0.179 has removed the CLI tool:
Remove Command Line version (thanks to SIF, not needed anymore)
I'd like to remind that the SIF is used for Sitecore 9 and later while SIM was used for the wide range of Sitecore versions including all the 8.x line. IMO, removing the feature is absolutely unjustified and just makes unnecessary obstacles for legacy projects relying on the feature.
Thoughts?
