This is voluntary right now. Here's the grammar:

(<XWIKI_CHAR>)+)* >
| <#MACRO_PARAMS: ( "~" ~[] | ~["}"] | "}" ~["}"] )* >

So }} is not allowed in a macro parameter. Otherwise there would be a
pb to know which "}}" correspond to the macro end (it would be harder).
BTW you only need to escape one "}" to make it work fine ;)
Note that quotes for macro values are optional right now and this is
the reason macro params are checked for }}.
We could decide that quotes are mandatory but it's a pretty big change
(would be for Syntax 2.1) and I don't think it's a good idea since
this your use case is pretty rare. And btw I still don't know if
accepting wiki syntax in parameters is a good thing or not.
