> significantly less time to run your optimizer,

Not necessarily, you work around this with JIT caches, which allow the optimiser not to start always from zero.

Additionally your can also AOT compile, with or without PGO data.

All modern bytecode implementations, at least for Java and .NET, use a mix of JIT with caching/AOT/PGO.

You can work around this in various ways yes (I'll add dynamic recompilation to your list of workarounds), but you're always going to have the problem of "Somebody downloaded a program and want to run it now"

Yeah, however in that very specific scenario it isn't about any winning SPEC benchmark suit.

Adding another workaround, shipping the JIT cache metadata alongside the program, and dynamically sharing it across all devices of the same category, as done in Android.
