Which observers are these? 

Brown thought he was going to lose in 2009, so just allowed the Parliament to expire at the end of the mandate in May 2010. I don't see anything different happening here, other than pointless media speculation which will eventually bore the public long before the event in January 2025. Despite being a media and pres geek, I don't think I could put up with it for 18 months.

No Government gives up early unless they think they're going to win. It's really quite self-defeating if you already have a large working majority.

2015 was as a result of the Fixed Term Parliament Act, which has since been repealed.  The GEs of 2017 and 2019 were because we had a small majority/minority government. None of those circumstances apply now. I hope the media don't become obsessed with speculation.

We don't want to all turn into 'Beryl from Bristol' saying "not another one". 

But just as you have one example of a PM running down the clock when they knew they were going to lose, there are plenty of examples too of PMs going to the country before they had to and losing. You can’t just take one example and claim that “no government gives up early”.
