I haven’t been able to find any information about the risk associated
with 8206895 (this patch), but the 8206265 thread you refer to reads to me
that a smaller, easily reviewable fix was approved for 11.0.1 due to stability
concerns right after GA, while a somewhat riskier but better fix went into 12.
If there were/are other reasons, I'd appreciate any insight you can provide.

It looks like a nice stability and readability improvement to me. Given that
it's been baking since 12, I see the backport risk as minor.

Please explain why this should be back-ported.
BTW, we already discussed backporting it to 11 here and it was rejected
as too risky:
Unless this actually fixes a bug, it looks dubious as a backport.
