I hope you will keep QTs out.
All design decisions are compromises, and yes there are valid arguments in favour of a QT feature. The arguments against QTs have the benefit of being backed by the reality of Mastodon's discussion culture, which we want to preserve and which was shaped by ruling out QTs.
9 out of 10 of those loudly demanding QTs have never asked how they might benefit from not using them. Their very loudness is the strongest argument against QTs.
