Hi,

DNF never makes RPM forget that some package is installed, I don't think 
there even is a mechanism for that aside from some forcing flags. It's 
all about

a) presentation to the user (like in list command we just don't show the 
hidden packages)

b) locking versions of the excluded installed packages

In particular, all the preexisting RPMDB constrains still hold after a 
transaction no matter the excludes:

[akozumpl at aklap ~]$ sudo dnf -x python-hawkey erase hawkey
Setting up Remove Process

Error: package python-hawkey-0.3.3-2.git506ff84.fc17.x86_64 requires 
hawkey(x86-64) = 0.3.3-2.git506ff84.fc17, but none of the providers can 
be installed
