This might not be universally beneficial if it ends up blocking other display blocking resources like CSS or images. This would put it at the absolute top priority by default by getting the implicit high fetch priority and being first before anything else can be added. Maybe this should be left up to user space, or maybe it should at least go last in the shell and maybe with It is in general more important to have the bootstrap than it is to have other types of JS like preinits coming from Flight though. Since you can at least do something with just the bootstrap but without it you can't do anything. |

right now explicit script preloads go before arbitrary preloads. But we at one point wanted scripts to go fairly late, behind things like images and styles. With styles we preload earlier if you are actually using a style. Fonts also have their own queue. But if you render a preload link it's currently behind explicit script preloads. So as it stands this could potentially delay preloading images and other media. But the way we were going to thread this needle I think was to emit preloads for things that were actually rendered above scripts. Would it make sense for a background image inside a css file to be able to flush with higher priority than a preloaded script? It would not trigger the "used" hueristic so it would look the same as a preload for an image we did not encounter during rendering
This is interesting but it stresses the Resource model because it doesn't have a good way to encode provenance besides the queue and we currently usually pre-render to chunks before flushing so changing things like fetchpriority after creating the resource is hard. I could make the rendering to chunks happen in flush (we do that with preloads for stylesheets because there is a high chance we won't end up flushing them) but this feels unforunate to apply to all preload resources |

stacked on #26753 Adds support for preloading bootstrapModules. We don't yet support modules in Float's public interface but this implementation should be compatible with what we do when we add it.
