I think there should be a toggle that makes it so your arm is thinner (or not) in the skin section of the account settings page. I recently encountered an issue where i used skin swatch to change my skin to a temporary one (so i wasn't using the default), and that skin had thin arms. When i later changed it to my new skin the thin arms remained and there was no toggle, so i had to change my skin to the default using SkinSwatch TWICE for the arms to return to normal.

I don't know if there are preexisting checks to make arms thinner based on the texture but still, i think a toggle would make this less of a headache.

Arm thickness is entirely decided by the client and is based on the texture file, the website has no bearing on how the client will display your skin.

client doesnt ask classicube.net for skin width?

No, it doesn’t. It downloads the skin file and tries to figure it out on its own

why doesnt it?

Because it doesn’t, never has, and likely never will. There’s very little benefit to the relatively large complexity increase.

I'd go so far as to say that pinging the website to determine the skin type would be a blunder, and was a blunder when Mojang did it. It makes much more sense for the skin file itself to be what determines the arm type, because the skins must be made specifically with one or the other in mind. They are not freely compatible between each other as it might seem if the user was allowed to choose the option when uploading.

so it wasnt added because its complex and the user might be dumb enough to pick the wrong option?

In truth it was just not added because it was complex. My opinion there is entirely my own (I'm not in control of the site features in any way)

It wasn’t added at the time because the classicube project predates the concept of the thinner armed skins.

It hasn’t been added since because there’s no motivation/reason to do so. The client can guess and display the skins differently depending on how the skin appears in the texture file, but there’s really no precedence for this feature in classic/classicube otherwise.
