I don't know why people defend software for their oversights or laziness. It really wouldn't be that difficult to offer optional buttons, unless Adobe programmers only use geniuses.
There are many features I'd also like to see - but I couldn't attribute their being missing as oversights or laziness!
I'm not 'defending' anything. I simply see no need for the feature you're describing and I wouldn't want an extra button for it.
An Eagle for an Emperor, A Kestrel for a Knave.
