REACH has been around for many years. Must not complain – REACH & ROHS compliance work has put the bread on the table for millions of people who would otherwise be queuing up for a bowl of soup on street kitchens for the homeless 
There are countless exemptions otherwise e.g. car batteries would be banned.
Of course, anything could happen, but the politics, versus implementation challenges, are not anything new.
Will have to invest in long-range tip tanks then. Because if 100LL is banned from EU I’ll have to make any flight over G.B. in order to refuel 
Just kidding.

Quite a few -540 variants seem to be approved for UL91, in addition to most -320 and -360 variants
I would be happy if UL91 was available at my homebase. Not only is it cheaper but also it stops getting fouled spark plugs. Quite a lot of engines are approved for it and unlike Mogas in most cases no STC or mechanical interventions are needed. We fuel it whenever we can.
There will be some invention to cover that problem. There always was
Apparently there is a 100UL available in Sweden?
Not sure if it is available but Hjelmco demonstrated a 100UL blend ca. 2009 already.

FAA has funded lots of research on this for at least a decade. Several companies are “almost there”. The problem with a 100LL replacement is that it must with 100% certainty work with every engine and fuel system approved for 100LL without the need for testing.

There isn’t. Only BP UL91 and Hjelmco 91/96UL.
Checking the Lycoming list the Comanche 250 Lycoming O-540-AIA5 may be UL91 approved? Making this one of the higher performance legacy designs that can use UL91. Some of the UL91 engines might be in the Twin Bonanza, and obviously the Beech 18.
