I actually have recently improved the keyboard lag you pointed out. I'm in the middle of a couple more updates and am hoping to put up a new build in the next week.
As far as your question about gamepads I think it depends on the developer and the type of game that they are trying to make. I prefer gamepads for platformers myself because I grew up playing platformers on console and am trying to make a game that 'feels' like it's from that era. (this is why I had been primarily focusing on these controls)
That being said I totally get that there's an audience of keyboard/platformer players out there. I want to do what I can to make those controls as tight as possible for you.
I think a big reason behind the trend of downplaying keyboard controls is that people often assume you don't have gamepad support unless you make it very clear that you do. So don't think of it as us saying "Don't use Keyboard/Mouse" as much as us saying "There are other options" to people who are less experienced with PC gaming.
Ultimately though I think it's just about creating the thing you are passionate about and figuring out the best way to make it accessible without having to cut corners.
