In full disclosure we hit a limit on 10.0.R2.10 with the number of AE links we could provision- 10. Additionally we saw the memory link error that is (apparently now) characteristic of running that code- we are now at 10.0.S1.1 (as advised by JTAC) and have 12 AE links working just fine. At this point we use interface-ranges so heavily that it would be a PITA to take the time to reconfigure everything without the ranges (and then reconfigure with them when we decide to go back to the 10.x train).
I'm not sure where (version) the memory leak is introduced in JUNOS but it's between the marvel chipset in the PFE and the RE. I think it was also limiting some of our VLAN creation.

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.
