To those people [who want the weather to exactly match the METAR] I’d argue that in real life the conditions don’t match the METAR exactly anyway, other than at the exact moment the METAR was taken.
If a METAR is taken every 30 minutes, the last one being 15:00z, at 15:29z it’s potentially completely wrong and almost certainly not current/accurate (It could even be totally wrong 1 minute after it was taken) 
So the weather system should change even though the METAR is the same, it should develop/progress as meteoblue forecast.
Another important point is how we transition to the new METAR data too, in the example above, we should slowly transition the weather e.g. between 15:00z and 15:02z
So the timeline would go something like this:
- 15:00z New METAR data
- 15:00z-15:02z Gradual transition to new METAR conditions
- 15:02-15:30 Weather develops using meteoblue trends/data using a METAR starting point and is biased to those METAR conditions (strong bias at first decreasing exponentially over time)
