That sort of signature change would break existing compile time
dependencies and cause build time problems. We can't do that at this
point.

While it is certainly true that users are suffering from the "binding"
issue, which has been present since 1.0,

You're not the only one. We tried to make UIComponent injectable and
ran into a lot of problems with state saving and the lifecycle. It's
too big a change at this point.
Thanks,
