the word purge is used under two different context with ee:
- to remove cached files (as in big red button on nginx page)
- to uninstall components (as in purge the stack)
what does ee stack purge do? The documentation sounds like it “REMOVES” packages, If that is what it does, i would ask why do we need a remove command then? I would also suggest, the word purge is perhaps not the best choice for removing packages, as removing packages is sort of a big deal, which breaks sites, unlike the purging of cache which does not break sites.
