Yes, I am actually trying that now on ACX7024X. I gave up on the 4650s for now. Strangely, I was running into the same kind of commit errors on the ACX and needing "bridge-domains" configured. You actually CAN configure them even though they are hidden from the list of possible commands like "set ?" or "set routing-instance yadda ?". If you type them in correctly, it will take the comment, commit and show up in the config. Working is another story. I have been trying to follow the Juniper validated designs, but they only give the mac-vrf config, not the interfaced logical unit config, vlan config, etc. So, I'm going it another shot today using VLANs.

Can you give it a try and configure a VLAN(s) inside the MAC-VRF?
Bridge-domains are for MX routers and equivalent with VLANs.

So the answer is using instance type MAC-VRF to do MEF E-LAN EVPN is not possible on EX4650 because a required feature/command bridge-domains to configure the service does not exist.

Checking on Feature Explorer it looks like the EX4650 does not support bridge domains. Which is why the option is not showing up in the cli.

The bridge domain is configured in their own hierarchy at the top level of the configuration.
This will then include the vlans and interfaces assigned to the mac vrf.

Has anyone had any luck creating MAC-VRF type instances to implement EVPN on EX4650 switches? I have had luck with EVPN on vMX using instancy type EVPN but trying on EX4650 eval hardware. I get errors like this even though the option to even create a bridge domain exists from top level, in the instance, etc in JUNOS on this platform. "bridge-domains" is not in the list of possible commands.
[edit routing-instances BD100 instance-type]
'instance-type mac-vrf'
bridge-domains must be configured for mac-vrf instance
[edit routing-instances BD100 instance-type]
'instance-type mac-vrf'
bridge-domains must be configured for mac-vrf instance
