Noiler manufacturers seem to insist on one, for the warranty. They do
only collect the rust particles - no use at all for collecting other
debris,

Some have a cyclonic filtration action as well for non magnetic stuff -
however their ability to "hang onto" the non magnetic crud is presumably
more limited.

which can still obstruct a modern boilers water passages. So
basically - if it needs flushing, it needs to be flushed before a new
boiler is fitted.

+1 or at least, it can be fitted, but isolated at its service valves.
