Open generic support for VContainer

[notargs]

Hi,
It seems that VContainer has open generic support in 1.14.0. (hadashiA/VContainer#367)
Are there any plans for this registration support in MessagePipe?

( NOTE: Requesthandler is still not supported.

I hope you will give it a try.
Any feedback is welcome. thx!
