I was skeptical at first when we made the change in SvelteKit. However, SvelteKit has a large integration test suite and being able to change the code and rerun the tests against the real final version of the code without waiting for any build step to complete has been a big improvement to productivity and I'm now a big fan of having made the change there. The tradeoff may be a bit different in Svelte core where we have more unit tests and fewer integration tests, so we're still investigating and considering the change, but we do have experience with both approaches and at the end of the day great software can be built using either approach.
