<p>I agree that if we want to have plugins sorted by their legality or other somehow dubious practices, separate repositories are a good way to go.<o:p></o:p></p>
<p>Plugins which only support a subset of possible platforms are in no way more nor less critical than any other plugin which claims to support all platforms.<o:p></o:p></p>
<p>The metadata we talk about here is not something to lookup by people on a regular basis, but for<o:p></o:p></p>
<p>- the plugin manager to check if it's suitable for the current platoform (i.e. it will not even offer me to install it on my Linux machine), just like Ubuntu won't even offer arm packages if it's running on a x86_64 machine.<o:p></o:p></p>
<p>- general information purpose on the plugin website<o:p></o:p></p>
