Absolutely. If someone changes existing manager commands like this,
then the AMI version needs to change.

Do you need the AMI version to change? My idea was that apps would use
AMI version plus Asterisk version for that. AMI version changes should indicate
that there are differents in dialects, Asterisk version changes that you might have
new features to use.
