Impact on EPP clients could be used as addtional measurement tool for 
version number changes.  EPP client implementations should outnumber 
server implementations by very wide margin.

Impact on existing client EPP implementations can be avoided or limited 
if version number stays the same. If version number is upgraded then 
client changes are necessary.

Server changes are required regardless whether version is upgraded or 
not. The scope of server changes is larger in case when version number 
is incremented.
