Freely offered weather is always good to have. I've certainly requested local and slightly further away weather from a couple of LARS providers in recent years.
That has made getting a picture of things generally much easier. But what it usually allows is a lot more flexibility.
The last time I was in this position I could have carried out a 180 turn and retraced my route, or it meant diverting a long way inland a long way off route. The station I was working would have no idea where I was off to - because I was not sure and so could not tell them - just that the weather they had given effectively blocked the route.
I told them I was going to try and route inland and left the frequency. Given they have radar, they probably watched my meandering route - but without that it would have left them wondering I guess.
