Me: Managed to figure out how to port that library. Just need designs and then we can build feature X. I've tested it in ugly developer-y screens. It works fully

Boss: Thats awesome, saw the video, looks great. This is a really important feature, thanks for looking into this

~1.5 years ago:

Me: Ok i've started working on the designs, just FYI we don't have designs for feature X

Boss: Ok, must have slipped, noted

~1 year ago:

Me: I've seen more posts about users wanting apps with features X in it. Still don't have designs, we working on that?

Boss: I'll check with design

Boss: Ok were going to have to get serious about pulling features out and reducing MVP so we can get this out there. I think feature A, D, Y and X have to be dropped for v1. Theres too much left to do on them

Me: sure

Boss: We need to start getting ready for xxxxx. Can you do me a favour and start writing up some developer docs etc, kind of like this one we did for this other project

This morning opening my emails from last night:

Boss: I've reviewed the doc, looks good, only minor things need tweaking. Let me ask you something though, you said feature X was pulled out and its "pending design work". Its not only pending design work is it? Is it that far along?

What I actually replied:

Yes ... i've sent you videos of it functional in the past, and discussed this ... more than once. Just design ... and some testing of the new designs obviously

==========
What that meant:

Yes. May god have mercy on your soul if you reply anything even remotely close to "oh I had no idea, lets revisit adding this to v1". I will not be held accountable for my actions
