I always have thought same.
AAVs are unnecessary & cause a lot of leaks, damage & call outs.
Stuck straight into hottest parts of boilers or pipework just guarantees they leak.
Manual vents are fine for a heating engineer, as he or she will know what needs bled when systems are fillled.
AAVs also cause air ingress if fitted on suction side of pipework.
