Mount Summoning Instrument Protection

This is a short suggestion.
A) allow /itemlock to work on mount summoning instruments (whistles, flutes, ocarinas) so when you can't drop/delete it and/or
B) Just make it a regular item. Why does drop destroy it? It's not like anyone less can pick it up. If you wanted to destroy it, then leave it behind in a chest or go to a rubbish bin

It's kinda weird how (afaik), they're the only items that get destroyed when dropped and can't be item locked
