I didn’t say they have more important things to do but that they can’t just stop what they’re doing and code a solution in 3 weeks as the parent comment was suggesting. It’s perfectly ok to have to wait more than 29 days to (hopefully) see new features released that address the letter.

They don't have to just stop what they're doing, they stop what a couple of people are doing and ship something. 29 days would be fine if they replied straight away. But they didn't they took ages, 29 days is a long time for a response. So if you take a long time to reply you have to have something to show why. As it stands, this just looks like they couldn't really be bothered and had it as a "do at some point" task.
