No, frankly it isn't. No matter how good the implementation of the

those who think that the mobile and desktop paradigms are not (or shouldn't
be) fundamentally different in some respects, but those people are
Mobile will always have special challenges that desktop may not face. And
the faster that mobile devices get, the more complex the scripts that devs
will want to shove down the pipes to run on it. You can't just wait around
for some mythical future time when mobile processing power is not a limiting
factor. The fact is, it's a limiting factor right now, and will be for any
foreseeable future. And so we're trying to find ways to juggle the costly
operations around to help mitigate the impact.
It's also tempting to just get mired down in this one use-case of mobile
controlling execution is important, there are plenty of other use-cases for
loading a script ahead of time and not using the script (parsing/executing
it) until later (or sometimes never).
