There were many apps which relied on register_globals but 
register_globals was introduced.
There were many apps which relied on references in PHP4, but the object 
model changed in 5, references too.
There are apps which rely on magic_quotes, but magic quotes are deprecated.
When some feature is changed or deprecated there will always be 
applications that need to change.
