How to remove a tree node?

Ext JS 5.0.1 just gets better every day. Apparently one calls .erase() to .destroy() a record nowadays.

Who dreams up these API changes? I can see no reason why "erase" is better than "destroy", it just creates work when upgrading! And all those people in the past who have previously said to me things like "everything 'just worked' for me when I upgraded" have me wondering if they actually create web apps that do anything at all!

Calling .destroy() didn't throw an error, yet still (partially) worked, but it's not in the docs. I dunno, I'm definitely seeing value for money in this 1,000% pricier framework.... not!
