Correct! In production we've got Cloudflare in the middle, so we're only using sucrase on-the-fly for each .ts file during development. So far it's unnoticeable in terms of loading times.

Not that I can tell. But if we need to, we can always do a minified bundle in production later on. So far it's just nice to not have to even think about it!
