Can you give examples for what is a "named exit", versus the other kind?

I've tagged (perhaps seemingly) hundreds of freeway onramps and offramps, 
including the exit numbers and names of the source and destination roads, 
in a scheme that has raised some issues. I've proposed to move those that 
I've done to a new scheme that is less conflicting here: 

In the case of moving some of the name=* values to exit_to=*, I noted that 
the name=* values are being rendered by Mapnik and Osmarender, and asked 
whether those (and others) have been modified to use exit_to=* instead, to 
which one user replied "don't tag for the renderer". While I understand 
that concept, it seems to me that the renderer was apparently designed to 
agree with the current schema, and I'm just asking if everyone wants their 
exit names to stop being rendered until someone decides to fix the renderers?
