Missing entitiy operator is:reply
If I want to filter for original tweets only I can use -is:retweet and -is:quote, but then I still receive tweets which are discussion replies. I can filter them out manually as a work around by checking for inreplytouserid values in the streams data fields, but having a is:reply entitiy operator would be very useful and save traffic and processing power on both sides.

is:reply is already there, like is:retweet it works on a paid premium not on free sandbox https://developer.twitter.com/en/docs/tweets/rules-and-filtering/overview/operators-by-product is:quote doesn't work for Premium, only for enterprise.
