I said "so many little things", not "this one specific little thing". Other things: I frequently get packages that offer themselves to be upgraded but the upgrade mysteriously fails every time I try it. No reliable way last time I checked to tell it where to install packages. It'll happily detect packages that have been installed outside winget (good!) but I have experienced cases where, when attempting to upgrade one of those packages through winget, it instead creates a second installation of it (horribly bad!!!)
Also it's not like apt, all it really does is download and run an MSI with a bit of fancy glue around it (which is why it can break so badly), you could probably install the latest version of this by manually pointing it at the right URL, so it's more annoying for it to be substantially behind.
Though in retrospect I'm not sure why I interpreted this as being "substantially behind"! It was more that someone made a vague winget lament and it struck me as an opportunity to express my evidenced belief that it is terrible :)
