Also it lacks some chipset-only features like user copper lists (This hopefully will be implemented someday), overscan support, sprite support (but fortunately nothing really uses sprites via graphics.library anyway) and so on..
It still works nicely as a replacement "loader" for most bootable games and demos and also it runs most system friendly games.

Yes, no. (and if it hangs or something weird happens = serial log required as usual)
Note that WinUAE version has extra compatibility hack, emulation automatically adds extra RAM to hidden addresses (that is marked as full after aros start booting), this trick frees 99% of normal RAM for program use without compatibility problems.
Normally aros boot rom would use too much ram to work with unexpanded amigas.
