The HeroIcons package approach works for client side frameworks but it doesn’t work for server side frameworks. With the package, we would send to the client the same svg several times, either in the same or separate pages. The way to address it by sending it as a regular image and have the browser cache it, as pretty much any server side framework does.
I am 100% certain that the new default provides better user experiences. Upgrading the icons is the only downside, but that rarely happens, and it is as easy as dropping a zip file. In any case, we are looking into streamlining it, potentially with a mix task.
