Sounds like GL drivers are going to cause me grief!

Ok, that is good at least. (Although only running under valgrind would
reliably catch if this causes problems).

No documentation, sorry. I've coded up a very hacky start for what you
want to do.. Unfortunately, the APIs I wanted to use to make PCB "find"
the connected objects are burried in find.c and not exposed sufficiently
for me to call them. I could probably have ripped out and duplicated a
load of the find.c code in the plugin, but I think it is useful as is.

Find the net you want to join. Hit "F" to "find" the connected objects.
(Highlighting them in green).

Run action "JoinFound". Presto.

You might want to hack the plugin's code to change the thermal style
number. IIRC:

1,2 = square ish thermals
3   = solid join thermal
4,5 = rounded thermals
