Some beliefs which are frequently displayed in these parts:
> Money on chairs / desks / PCs are no object because developers cost money, not those things
> Ship quickly and iterate
> Make it, make it work, make it fast
> Write code your successor can maintain
And then HN goes ahead and upvotes a boast about spending their (expensive) time unpicking libraries from code.
The point of "you might not need X" is to encourage package maintainers to keep their sub-package footprint small, not that end-users shouldn't use X.
I'm sure you'll be back to suggest that you've delivered "500% speed-up" or some other nonsense metric and I look forward to that.
Ultimately, custom business owned code which attempts to deliver the value of angular is just a future maintenance nightmare, and I say that as someone who really doesn't like angular.
If you really replaced angular with a "javascript one-liner" I'd like to see that line!
