Someone I know who is an electronics tech told me a few weeks ago,
there were plans to end the use of the "wall wart" or "line lump".

These are of course the small 3,6,9,12v AC or DC power packs that are 
used to run all sorts of things.   The problem is, what are they
going to replace them with?

Also I have a lot of gear (music equipment) that is quite fussy 
about what kind of annoying wart or lump it needs.  I actually hate them,
so on one hand, I do welcome the move, but otherwise, I still want
to be able to use my old gear, because it's not obsolete.

So somehow, I am a bit concerned by this move.

I have already purchased one bit of gear that is now ROHS compliant,
in that it is made from lead free solder.   The engineer who designed
it (it's a high end audio mixer) said that ROHS was a pain in the bum
and it took them a lot of time to get the formula right.

At least the Japanese and other countries backed down a bit on 
rare electronic musical instruments being banned as a result of the 
ROHS stuff so that is OK to possess gear with leaded solder but
new stuff must be compliant.
