We can agree to disagree, but effectively turning PHP into an
optionally-typed language - which Nikita's patch does a HUGE step towards
(IMHO a much bigger one than scalar type hints did at the time) is more or
less a singular event.
And no, I'm absolutely not encouraging us to come up with additional
language-changing features just for the sake of marketing - there's a world
of difference between timing the rollout schedule of what we intend to roll
out anyway, and adding extra bells and whistles just to make the new
version attractive.

I didn't hint at that, at least not intentionally (I'd say 90-95% of the
feedback I've seen for PHP 7 was about performance, and 5-10% was pretty
much everything else, but that's beside the point).
What's on point is that new or improved capabilities are the draw into new
versions. The more (sensible!) of those you have, the better. Wasting our
'ammo' on the 7.x line at this point is, IMHO, a mistake. I guess I have
much higher levels of self control and patience - as this is precisely what
we're not going to do with the stuff we've been working on (JIT, FFI, and
phpng in the past).

Maybe it feels that way, but it really isn't. I'm not sure whether you've
had the luxury of contributing to the PHP engine, but working on two
simultaneous active branches with substantial data structure differences is
an unholy mess (it's also way, way worse than working on two branches of an
average PHP project). Even if all of the developers are focused on PHP 8
it's going to be a remarkably difficult feat to achieve. Throwing in
another parallel version that we'll need to work on at the same time is
shooting ourselves in the foot.

Please don't put words in my mouth and then call them disingenuous :)
I did not say we should 'block any other features'. In fact, in my
blueprint for PHP 8 - I said it's clear to me we're likely to see
additional ideas that will be proposed for PHP 8. It's an extra feature
release that will divide our resources that I'm arguing against.
My logic is quite simple:
1. Something as big as Typed Properties shouldn't be a last minute, rushed
RFC. Really - any RFC shouldn't - but in particular major language changes.
2. We should not have a 7.4 that divides our resources(*); Much like with
5.6 -> 7.0, we should focus on one feature version at a time.
3. We're better off saving Typed Properties for 8.0 as another draw - and
we can also make it better by that timeline (a comprehensive typing
solution, and not an incremental one).
I am sure that's not your intent but those two statements together

Where did I say we should minimize features for 8.0?
