There is also the fact that while the bb may be perfectly serviceable now it can seize in there and be a real pain to remove when you do need to.
It's been in there ten years so I would remove it and grease the threads and reinstall.
But that's me.
Preventative maintenance.
If it is seized now at least you know and can make a plan.
If it's not, great.
