Preact, Mithril, Zod, etc. There are plenty of projects that have remained relatively light by saying “no” repeatedly to things which are outside their scope or would introduce unwarranted bloat.
Looking at latest version of Preact v 10.5.14.zip (887kb) vs Preact v8.5.0.zip(90kb). So that is almost a x10 size increase in two years.
