I am aware that the way I work is not the only one, of course, but I am also not so sure about your "vast, vast majority" thing.
You can call it dev-first mindset, I call it a sustainable work mindset. I want the people I work for to be happy with my output. Not everything is velocity. I worked in high-velocity companies and ultimately got tired and left. It's not for me.
And it's not about code being beautiful or other artsy snobby stuff like that. It's about it being maintainable really.
And no I am not given much of a time, I simply refused to work in places where I am not given any time is all. I am a foot solider in the trenches just like you, I just don't participate in the suicidal charges. :)
