Yes, ’quote boosts’ are a great example of this. Interestingly (but far from surprisingly) most people who want them don’t choose the fediverse services that already support them.
Instead the hope is that the software that doesn’t have it, and has long had a clear stance on not implementing them, will still build them if enough (or the right) people demand them.
If people truly acted the way you described with regards to the fediverse, wouldn’t they just choose another service?
