The example that I posted in that other [parallel thread](https://discourse.julialang.org/t/new-julia-versions-higher-pluto-loading-times/135187/8) shows that, at least for that package, nightly jumped compile times by ~25 % from the not-yet-released 1.13 to nightly, so there is (way) more than bounds checking.
