Apologies for the lack of a personalized message, but I will be contacting a number of modders today.
Your mod, Inventory Hotswap, is one of the few that can't be downloaded by third-party launchers and other tools.
With the following GitHub Gist I would like to try changing your mind, and those of other creators.

Thank you for your work! 💚

I didn't even know this was disabled, I use polymc myself. I've enabled it for all my mods.

Sweet, thank you!
