Is it planned to add count argument to `collect(every:on:skipEmpty:discardWhenCompleted:)`?

[Chase Choi]

I'm trying to find a built-in operator similar to bufferWithTimeOrCount(timeSpan, count, [scheduler]) in RxJS, but I only found collect(every:on:skipEmpty:discardWhenCompleted:) and collect(count:). Should I create my own operator?
