[Interest] Signing Qt DLLs

[Bob Babcock]

Qt packages I download from www.qt.io are digitally signed by The Qt 
Company, but Windows DLLs inside those packages are not signed.  I have 
purchased a code signing cert.  Is it ok if I sign the Qt DLLs distributed 
with my application?  (The app is GPL and it uses otherwise unmodified Qt 
DLLs.)  Is there any chance that Qt might start signing its DLLs?

The reason for wanting everything to be signed is that Windows Defender may 
flag unsigned executables as possible malware.
