They are doing fine.
There are still builds being put out on an almost daily basis (last build was Friday, I admit that was the 13th so it might have been one with a potential huge, still unknown, bug in it). Those builds contain both new features and fixes bugs.
Despite popular belief, we are not the ones deciding what the team is going to work on. Instead SE has paid staff that is tasked with product management and they will prioritize and assign tasks to devs and designers to work on features. Sure product management might check if ideas posted on Meta can help shape a feature but that is as good as it gets.
With the 453 feature requests with a status-review there is plenty of attention from SE staff for features.
Given there is an almost unlimited amount of users that can write and post a bug report or a feature in minutes, no number of SE staff will be able to attend to all these posts in a useful manner. Let alone implementing.
Instead of demanding response or demanding that stuff gets answered and/or implemented, how about we just post feature requests with a different mindset. Don't post as a request but as a suggestion. A suggestion is just that, a suggestion, nothing formal, nothing designed to the final nitty gritty details. Don't pretend the world ends if your silly feature doesn't get resolved in 6 to 8 weeks. The product we use is not paid for. For something that is free to use we get pretty well served.
