"Unknown publisher" for uninstaller UAC prompt (only windows setup exe signed, internal files not)

[terminatorul]

When installing Electrum, the UAC prompt for the installer shows a blue pop-up message with "verified publisher".

But when uninstalling you get a yellow prompt with an "unknown publisher" message

I guess it's because only the installer/setup exe is signed, the files that are unpacked by NSIS are not.
So e.g. the uninstaller exe, but also the internal starter exe, are not signed.
I expect it might be problematic to sign these while keeping the ability that anyone can verify the reproducibility of the binary.
