Chugs,
Sometimes we tinker because the end-user wants us to, not because we are all sitting idle thinking, "I wonder how I can tinker with that?"
There are lots of good reasons for tinkering with COTS equipment, not least because 1 size usually fits none.

COTS doesn't necessarily mean 'overseas'. We can still go COTS and keep UK jobs supporting British Industry. So your opening argument/point of debate is flawed.
