I'm not sure what you mean here by "should be". If you mean "if
everybody dropped everything right now and started only working on
upgrade to PHP 7 then they could make it in 20 months" - yes, it is
reasonably true. But nobody would do that. In fact, in many places base
version is still 5.3. Again, we can talk that people "should" do this
and "should" do that until we're blue in the face, but that's not going
to happen, whatever we talk about. Only one of the two things is going
to happen:
1. People would run 5.x in 2017 as supported version and get the fixes.
2. People would run 5.x in 2017 as unsupported version, get no fixes and
suffer from it.

We don't know that about 7.0, but it's not the first version we've
released. We know what happened with previous versions. So please tell
me, based on that past experience - does the scenario of "majority of
users are running 7.x in 2017" sound realistic?

> Furthermore, postponing EOL now means reduced pressure to upgrade to 7.

Again, if you think people's decision to upgrade significantly depends
on that, I think you are deluding yourself. We have tons of "pressure"
to upgrade from EOLed 5.x versions. We still got majority of people
running them, and more sites running 5.2 than 5.6, judging by
