Not handy. Miguel said that CLR's support for struct's and generic types

That sounds more like an implementation/maturity issue. More effort put
into CLR runtimes could make them better.
Indeed, the CIL has a number of features that are designed to increase
the performance over the JVM. For example, at any given point in the
bytecode execution, the CIL requires there to be the same number and
types of items on the data stack (if I recall correctly), which
apparently makes it easier to generate better JIT code by allowing some
of those locations to be assigned to registers, for example.

It's not feature creep if you put it
at the end and adjust the release date.
