I've been told that the only limitation is the FIB size, or every VLAN
(since the EX doesn't support multiple bridge domains).

In practice, if you're doing that, it implies you might have a large
L2 config.  We have hit a number of bugs related to the CPU time it
takes to commit a large L2 config.  Turns out that can spin enough to
interfere with periodic packet processing.

So - it should absolutely work.  You definitely want to be running
9.6R3 as it has a fix for a potentially serious scheduling bugs related
to large layer 2 configs.  It's been decided that this fix will NOT be
backported to 9.3.
