You and Noah have been clear on that point, which is enough to make
*me* careful with any Unicode updates in the future. I'll suggest once
more that you say so in the policy thread here:

https://www.postgresql.org/message-id/d75d2d0d1d2bd45b2c332c47e3e0a67f0640b49c.camel%40j-davis.com

which would get broader visibility and I believe provide you with
stronger assurances that *everyone* will be careful with Unicode
updates.
