Well, you can argue for both, really. The same argument, that a custom ROM has to be maintained specifically for a device and that’s a downside could be flipped upside down, stating that this ensures, that a custom ROM really runs smoothly on that device. With GSI, you don’t get one-on-one support for your specific device. Because, as we already mentioned, the whole purpose of GSIs is to make the image available on more phones. Now, that doesn’t need to be a bad thing, it can just mean that if a problem occurs, maybe it’s a bit more difficult to find help for your specific problem or your specific device. It could also be easy. You never really know.
