Or give us actual syntax for blockquotes? (> at the beginning of a line, markdown style, would be great…) Which I feel like gets used all the time in the discourse here, and for good reasons, too.

Then you would have that bit of time back, and the rest of us could stop scrolling back and forth when someone code-blocks a blockquote.

Or write a bot to do it automatically everywhere

Or fix the CSS

The monospace is, I think, intended for code, and a lot of us use it that way.

You want something separate for code blocks and block quotes here.
