Thanks for the feedback and review, I've updated the pull request accordingly.

About the rationale: adb and fastboot are two tools very widely used to flash (fastboot) and debug (adb) AOS-based devices; they're indeed part of the AOS SDK (which is a huge package).

What you may often want is just "flash" a device using fastboot with a blob and connect to it with adb; installing the whole AOS SDK for this whould be a major overkill.

Providing a package only for adb/fastboot is a pretty popular approach on many other platforms.
