Our timeline being agressive to cause more intense work on our
people is one thing.  It does not make much sense to me to compare
it with the timeline being aggressive to others who do not control
our timeline.

Putting it in another way, I'd call it hopelessly optimistic to
expect that those currently without Rust can somehow come up with a
plan to help their vendors (or they may be vendors themselves, then
convince their management) prepare their platforms to support Rust
within 18 months.  And giving them ultimatum based on the optimism
was never my favorite part of this whole thing.

I figured that something like that happened.  I was mostly
interested in how firm those original authors supported the version
with Ezekiel's changes, as outsides would not be able to telll how
extensive the change were.

Thanks.
