The actual changes LGTM for cognitive overhead but I'd love to see a benchmark showing a measurable (even if small) impact.

I get why this would matter for require in userland but I'm not sure I understand why it would impact load times here.

It is difficult to measure this with a small change like this alone. If you have a look at #20567 you can see that lazy loading does indeed significantly improve the performance. We still need snapshots but lazy loading is already a first good step and a good thing in general.
