Could that procedure not backfire, if the last line would
still fit, but an .ne forces it to the next page?

Here is a different trick, but it needs specific end-of-paragraph
macros (which could probably be called automatically from all
block-level macros) and it (ab)uses the line-numbering feature
to count the lines of a paragraph, so no luck if you need line
numbering as well:
