Android and iOS have empty functions for check_requirements(), and I think that's the right way to go. Never really discussed it on list though, so wanted to share why I think this.
Originally, the motivation was to run some checks *before* downloading the platform. It turned out that downloading platforms is not very expensive, and having the platform requirements check code both in the platform (where it is needed) and in CLI (copy & paste job), wasn't adding much value. So... Platforms changed to lazy-loading first, then calling out to the check() within the downloaded platform. Now, since platforms scripts all work without CLI, it's important that commands like `create` call check_requirements themselves before running, and as far as I'm away, most platforms do this. So... now we've got the same check() function being called twice. First by CLI's check_requirements(), then by the create() script itself. So, I think the best thing to do is just delete check_requirements() from CLI and expect that the platform scripts do some checks themselves.
