Actually those crossings are not called AHOBs, but ALOB 'Automatische Lange Overweg Boom' or for you english folks 'Automatic Long Crossing Barrier.
Where did you get that information? I have never seen this term ALOB, and I also can't find it on Google, except in a small youtube video of a Coha.nl simulation of a crossing that would never be build in real life in NL, as it also closes off the exit of the crossing;
https://youtu.be/G7EFpGpxJs4. The the comments below it, they claim Vialis made up that (ALOB) term. But I have never come across it in documentation about railroad crossings, and I have been involved in several crossings (also some that are yet to be build).
In fact; it will officially be called an AHOB, as long as it closes off only one direction of traffic; also if the barrier is long enough to close off two lanes at once (then those lanes will always both be for the same direction).

Also, I don't like that M5 has ZUB cab signalling (I use thru trains on line M2/M4 during peak times for platform capacity)
But I like ZUB colourlight signals ¯\_(ツ)_/¯
'Why don't we have both' (from a Taco ad)
(ZUB signals and RET ATB), even if it's only at absolute signals, like LAmetro says he wants
That wouldn't really be usable with these block lengths; I could install ATB transmitters in the track, but if you are driving to a red signal, you would have to travel the entire distance at 10 km/h, until the signal clears. With ZUB, you can approach a red signal at 80 km/h, and start braking before the signal, to stop in front of it (the ZUB telegram you recieve at a yellow signal includes information about when the train must have slowed down, so you don't have to do that directly).
The current block system on line M5 is not suitable for ATB; I would have to rebuild the line in the CVL too, to add more signal blocks, as I have done on line M4; that line now has 3-4 times more blocks between Noorderpoort and the Rijndam Airport then when it had ZUB; just to prevent long distances at slow speeds.
On the museumline, I did install both. But only so the RSG2, which is now also a museumtrain (sadly; in reality they have all been scrapped), can run on that line. And adding ZUB to an ATB line is easier then the other way around).
