One peculiarity of this new post-arrival testing policy I'm somewhat perplexed by is the ability for a self-isolating traveller to escape quarantine on the 5th day with a rapid LAMP test, of questionable efficacy, only to then be found to have COVID on the 8th day after their arrival when they take their mandatory gold-standard PCR...

It really makes you wonder... Are the UK govt just requiring tests post-arrival - at great expense - to erect financial barriers to travel in lieu of legal ones?
