I cannot quite understand the 'aversion to'/issues with idle reverse
1) as FA10 says, the deceleration will be identical with and without reverse if autobrake is used, and
2) LDAs are checked for the reverse idle condition.
The only time 1) is not true is when braking action is compromised, when you would not be using reverse idle anyway.
As Dr F says , by the time you might realise you should have used it, even from a high idle you have troubles.
