I don't mind deprecating unused types.  But I don't understand how an
unused type can affect compression.  I can only imagine it having an effect
if the type actually exists in a packet, which means that it is 'in use'.

Do you mean 'types that have DNS records, and hosts query for those
records, but we think they are not really used'  ?
