My feeling is that they only cause annoyance to administrators if the
checks are not working correctly, personally if I have lame reverse
zones I would be very happy if the NCC ran a service that warned me.

I'm not aware of any study either but I think we are all aware that
certain applications work much better if reverse DNS is setup and
functioning correctly. If those applications no longer had a
dependency on reverse dns working then I may find it easier to agree
with your point of view.

As I remember there was a lot of support for this work around the time
of the publication of ripe-400 and my feeling is that providing the
checks are being done in a sensible way and they are documented that
this support is still there.
