I agree - for some reason when this issue was discussed before; I  
mistakenly got the impression that it was too hard enough to be implemented  
any time soon, so that my \hideNote patch was still worth submitting.   
Having said that,

  \once \hideNotes

is almost as much typing as

  \hideNotes [...] \unHideNotes

so for me ideally we'd have the best of both worlds, i.e. property-init.ly  
containing

  hideNote = { \once \hideNotes }

(and possibly others) so that the syntactic sugar is available, but its  
internal implementation avoids any code duplication.  If people are in  
agreement, most of my patch is still valid, since it's mainly changes to  
documentation and regtests - the implementation is only one small hunk  
which can easily be changed.
