Please don't misleadingly reference/quote me.

I made it quite clear in my last post that because segwit is a backwards
compatible soft-fork, the vast majority of code out there will not have to
change; my own OpenTimestamps being a good example. All I'll have to do to
prepare for segwit is upgrade the (pruned) full nodes that the OpenTimestamps
servers depend on to determine what's the most-work valid chain, and in the
event I was concerned about compatibility issues, I could easily run my
existing nodes behind updated segwit-supporting (pruned) nodes.

Like most users, my OpenTimestamps code doesn't "fully understand" transactions
at all - I rely on my full node to do that for me. What it does understand
about transactions and blocks remains the same in segwit. I can receive
transactions from segwit users with lite-client security without any action at
all, and full-node security once I upgrade my full nodes (or run them behind
upgraded nodes).

Your proposed alternative to segwit - flexible transactions - has none of these
beneficial properties. And as Matt Corallo reported, it's no-where near ready
for deployment: three buffer overflows in 80 lines of code is a serious
