In the example quoted above, like:

Ok, do I understand it right:
in the ex. 1 above, a score is created at '{ \harmonicsOn' and that has
no effect, because \harmonicsOn only applies to Voices.
Then the 'a' creates a Voice context and this does not know about the
\harmonicsOn.
That sounds a bit like a trap for beginners.

With that information, I thought the following would yield the same
(since there is only one Voice in the Staff):
\new Voice { \harmonicsOn a \harmonicsOff a }
\new Staff { \harmonicsOn a \harmonicsOff a }
But it doesn't. In the Staff context, the \harmonicsOn works, but the
harmonicsOff does not (probably, because there is a Voice by then and
the harmonics are set on staff level before and the Staff settings
override the Voice settings).
> \new Staff \with { \harmonicsOn } ...
With that syntax being possible with the current version, I would
suggest to consider a change, because the current implementation has
serveral pitfalls.
