Hi Marc

You need to consider your own maintenance burden. You want your local
branch to be as near to mainline as possible. Each change you have
means additional maintenance work for you. It also possibly means
additional work for your customers.

You seem to think flow control in your hardware is too broken to be
usable. So you probably want to submit a patch to mainline disabling
it. If it is accepted, that is one less patch you need to maintain.
