Everything that formerly used canistered fuel in py (salt, antimony, etc) now uses directly piped fuel. It'd be nice if the fuel could be directly burned in the powerhouse, which would enable sushi-fluid fuel input better than a large collection of barreling machines to fill canisters.

I have not being playing in a bit. So I wasn't aware of those changes. So what ARE canisters now used for?
I will have a look and might change it, yeah

They are only used for fuel for T2 trains or cars. You theoretically can use them as solid fuel for other things, but it's not an optimal choice.

I just uploaded a new version with this change. Sorry it took so long
