The use case is slightly different. I prefer to send read receipts, but I also like to peek at messages without sending them and removing unread counts because I want to add the message to my mental queue, but don't want the false impression that I didn't bother to answer the said message.

Ah, you want to read messages without letting the recipient know you've read the message, while still having read receipts enabled. I'm not surprised WhatsApp does not support this one, I think they want their users to be able to trust the read receipt indicators

Actually it supports that, via notifications and peek. The intent is not nefarious, as I said before. I don't want the person who sent me the message think that I read their message and just tossed to a virtual bin.

I just did it yesterday. Somebody sent me a message, and I read it via notification, but they don't have the receipt yet. I'll write their answer with a fresh mind, and send the answer they deserve.

I don't think valuing the person on the other end of the line is a bad thing.
