Changes bringing interface down in Junos

I don’t know if there is any comprehensive list of changes which brings down an interface apart from specifically disabling the interface.
So far I recall two of them which are striking and might not be expected to flap interface. If anyone has also experience, it might be a good
place to share.

per-unit-scheduler
Years back I didn’t know that this change (i.e adding or removing this) was flapping the interface. If you have any routing protocol or any other component depending on the interface, be aware!

MTU change
If you change the MTU of an interface and again if you are running e.g BGP you will see a flap as traceoptions will clearly tell you that interface is going down.

Any other change you know affecting interface status? Please feel free to share!
