I agree, but I'm two months behind on implementing important features. While I can take a week here and there to optimize, my time is best spent delivering business value.

Unless you allow performance to genuinely suck (and I don't) slimming down web apps won't help my business make money. You get what current fashionable JS frameworks and build tools give me.

As long as your customers are in the vast majority accessing your web apps over non-cellular data connections this makes sense. As more folks are cell-phone-first, ignoring the size of the payload you expect users to accept will increasingly represent a sub-optimal experience.

Well, to be fair, celular connections are also getting better.

[mattlutze]

It's not a question of cellular connection quality but of data quantity on a plan.

But you're not the one implementing the frameworks. For those, being slim is business value.

also, page size is not the biggest performance killer. too many http requests (for example, requests out to CDNs and advertising networks) is a more likely source of problems.
