The RIPE NCC has started allocating /22s from the last /8 on 14 September 2012. Since then 4190 IPv6 allocations have been made, out of which 1160 are currently visible in the BGP routing tables.
If we take into consideration the total number of IPv6 allocations made by the RIPE NCC, 8398 IPv6 allocations have been made, out of which 4098 are currently visible in the BGP routing tables.
That means that more than 27% of those IPv6 allocations are really used; and that's a quite impressive figure. And I think we can conclude that the current policy does have a positive effect on IPv6 deployment. In comparison about 49% of all IPv6 allocations are visible in the BGP routing table; and that makes that 27% even more impressive.
I disagree with your interpretation: present in the routing table does not imply being used. I used to take it as a good sign, but now I believe it is a very low bar - someone thought to apply for the address space and succeeded in configuring a BGP session somewhere. Maybe they really use it and maybe they don't; it's just not a very useful metric. Note that "arguments supporting the proposal" says that the status quo is actively troublesome for users of IPv6 PI space: to get a /22, they have to disrupt their IPv6 installation to return their PI assignment and get a PA allocation. Having this in policy is currently doing harm to IPv6, and we can do better outreach than this.
