The no Break Solution works for me in almost all of my publications, well over 100 per year.
It may not suit everyone, but it's one possible workaround that can come in handy for other people.
Yes you can search and replace for the forced breaks, but if you avoid using them then it's better.
The problem with forced breaks occurs for me in the "running headers" a forced break will incur an added space in the running head of each page, which is not desireable, and a forced break in converting to epub, and double spaces in all running heads is a nightmare.
Invoking a no break rule for say the last 3 or 4 or 5 words in a heading only at the end will mean that there are no extraneous spaces, or forced breaks in TOC and the epub conversion goes perfectly well.
That's just my particular workflow - it may not suit everyone.
