R&Rs have the answer - TL;DR is no change for back bets, limit reduced for lay bets

10.4 Adjustments to SP bets for non-runners

For SP back bets, Betfair will at no point amend either the stake or the odds requested by a customer, despite any non-runners or withdrawals. However customers who have selected the SP limit option can reduce the minimum SP odds they are prepared to accept on a selection.

For SP lay bets on win markets, Betfair will reduce a customer's liability based on the reduction factor(s) of any non-runner(s) and the reduction factor of the runner on which the customer's bet has been placed. This is to ensure that the balance between the backers' stakes and the layers' liability reflects the revised market after the runner has been removed. For example if a horse with a 50% reduction factor becomes a non-runner, then another horse in the same market priced at about 5 (i.e. a reduction factor of 20%) will change to a price of about 2.5. Therefore the liability on a £200 lay bet on that runner will need to change to a liability of about £75 to ensure that a balancing back bet will have the same £50 stake. This is done by multiplying the liability by 37.5% (i.e. 100%-(50%/(100%-20%))).

Where an SP lay bet in a win market has a maximum odds limit specified, this limit will be reduced by the reduction factor of any non-runner, if the non-runner has a reduction factor of at least 2.5%.

For SP lay bets on place markets, Betfair will still reduce a customer's liability based on the reduction factor(s) of any non-runner(s) but the calculation will be slightly different, in line with the application of place market reduction factors. The liability will be reduced by the reduction factor of the removed runner. Where the lay bet on a place market has a maximum odds limit specified, the potential winnings on the bet (i.e. the odds – 1) will be reduced by the reduction factor of the removed runner.

Where an SP lay bet in a place market has a maximum odds limit specified, this limit will be reduced by the reduction factor of any non-runner.

SP lay bets will not be cancelled when there is a non-runner.

"if min odds not met all bets cancelled regardless if nrs or not"

For back bets, that how I understand it.
