I talked about most of these in [0].

While weak hash tables are fully functional, there is a subtle
difference in how they behave that I haven't addressed yet [1].

Apart from that, the only incompatibility I know of is the lack of
`gc-live-object-stats', which can certainly be implemented but is just
slightly boring to do.  ;-)

Thanks,
