that's a fairly good interpretation of

https://tools.ietf.org/html/draft-fujiwara-dnsop-avoid-fragmentation-02

and also this, which the above draft will reference in its next version:

https://tools.ietf.org/html/draft-ietf-tsvwg-datagram-plpmtud-22

a flag day would mislead some, fix little, break much, and prepare for a 
future worse than the present or past. i remain opposed to this plan. as the 
person who recommended fragmentation in EDNS0, i'm here to tell you that the 
problem is more important and more widespread than just operational practices.
