We can do that when we package Qt 6.3, because we'll have new binary
packages anyway then.

Which package name do you suggest ? We already have " qt6-image-formats-

The only place where these are used are in Qt Network, so the plugins
should be shipped there. We can do that in the current packaging with
the proper Break+Replaces.

QImage is part of Qt GUI, so they should be there.
