I think it's best to leave code unminified as you say. Pretokenisation is on by default is effectively a very simple minification anyway.
Sometimes it does make sense to minify - for instance you may have some code that needs to run as fast as it possibly can (or to be very small on the watch) - and then of course having minified code on the device can be good.
But unless you really do need that, I'd just leave the code as-is. Often the speed difference is very minimal, and it's not worth the hassle of maintaining the minified code.
