> That's not an elegant solution, this is a stray markup disaster waiting to happen, and in both directions: re-wrap a paragraph (I'm doing it all the freaking time), edit some more so you can't just ctrl-z, and now you've got those plus signs sprinkled throughout your text mixed with non-special plus-signs.

Trailing + for breaks is for one-offs exceptions, usually with semantic reasons. If you are manually flowing a paragraph for some reason (mostly, that’s an antipattern, but...), rather than indicating a single special break, where “rewrapping” is a thing that makes sense, then using the [%hardbreaks] directive on the paragraph makes sense; there's also a document-level toggle in the header if you want to do this for a whole document. (And many of the contexts where you'd want hard breaks have their own block type, with other linked formatting changes: literal, listing, source, and verse blocks.)
