"Footgun" comes from the English idiom "to shoot yourself in the foot", which means "to act against your own interests" (usually accidentally). (Consider similar idioms, like "to dig your own grave".)

I think you're being a bit too literal. It's not an analogy at all, and this has nothing to do with firearms best practices. If we were to define a footgun as "a gun that is only capable of shooting you in the foot" (or perhaps more broadly usefully, "a gun that in theory can be useful, but it is nearly impossibly difficult to make it do anything other than shoot you in the foot"), then the entire point of using the term is to describe something that has no useful, logical purpose, and is unsafe to use, even as designed.

Being "given enough rope to hang yourself" is indeed another good idiom to use for things like this, but the implication is different, I think: when you're given enough rope to hang yourself, the outcome is still very much in your hands. You can intentionally or unintentionally use that rope to hang yourself, or you can be reasonably expected to use that rope in another way that would turn out to be safe or useful.

"Footgun", by contrast, is used to describe something that has no (or negligible) safe uses. Maybe the original intent behind the design of what's being described that way was to have safe uses, but ultimately those safe uses never really panned out, or were so dwarfed by the unsafe uses that the safe use isn't worth the thing existing in the first place. But, unfortunately, there are some people -- maybe only 0.01% of people -- who are able use it safely, and critically depend on that safe use, so we can't completely destroy all these footguns and save everyone else from the error of their ways. And unfortunately most everyone else sees these 0.01% of uses, and believes they are so useful, so efficient, so brilliant, they want to try it too... but in their hubris they end up shooting themselves in the foot, like most others before them.
