[js] About of deprecation of "old style"

[zorn-v]

What if I need just standard confirm dialog and then do something simple ?
In propagated method I need to "do webpack preparations and other" and all my scripts will include ALL code (I doubt about tree shaking, it is just not possible here). Instead of using OC.dialogs/OC.Notification I must include it im my plugin. And bring up useless npm, webpack, other... I just need to include ONE script with confirmation IN ONE CASE. Why I should build useless application bloated size of my app ?
