Not "new" doesn't mean boring. Boring means not using a technology (a framework, or a language) when not needed. Don't use Javascript on the frontend, when not needed, stick with one CSS pre-processor, one database, one cloud provider, one orchestration tool, one CI tool. Be frugal with your stack, and it will payoff.
Agree with the sentiment but, one CSS preprocessor (!!) Lol I must be getting old, CSS3 is amazing why do you even need one?
That's a totally optional component that now needs to be updated, used in your build pipeline and Lord help you if you install it with npm and it isn't updated for a couple of years.
I'd add boring really means boring, yes that kind of boring (zzz) ;)
