SQL 2012 CLR and XMLSerialaztion - Is UNSAFE still required for CLR's That Call Web Services

I'm learning to create a CLR assembly the "hard way" - Code the dll then use the Create Assembly T-SQL command.

In many of the 2005 and 2008 samples I've seen, there mention of using Sgen to create XMLSerialization code for dlls that call web services. Is the UNSAFE security switch still required in SQL 2012 for registering dlls that have separate XMLSerialization dlls created by the .Net Sgen component?
