This is a matter of opinion. We see daily that popular opinion or even
purported evidence can be very unreliable and as such prudent to be

Others would consider this exercise of good judgement and it is the current
softlanding policy that reserves /12.

Softlanding-bis proposes a /13.  Please see FAQ again  -

Setting the /13 aside for community to decide what to do if the need arises
really should not be an issue.  "Saving for a rainy day" is what good
custodians do.

You have also argued that any need for V4 will be superseded by IPv6
deployments in no time and having less v4 in the system will speed up IPv6

Hardly .... but we seem to agree that transition should be the focus in
exhaustion.   I wonder if converting the /13 from "unforeseen" to an
explicit reserve for transition to IPv6 will be more acceptable?

We have different circumstances in AFRINIC but I am thinking along the
lines of the dedicated /10 set aside in ARIN for IPv6 transition -
