It’d be awesome to be able to have the ability to use a CCR1016 (or other non switch-chip L6) to act as an L3 switch using VLANs on a Bridge (for 802.1q trunks)…currently untagged traffic roots to the CCR…but VLANs have no presence in the STP.
Thanks for listening! 
+1, (R)STP for the VLANs would be handy.
Yes - Missing PV-RSTP (Per VLAN Rapid Spanning Tree) stopped me already a bunch of times using Mikrotik and go Cisco instead…
Further down the Road, ERPS would be great also - especially on the FX CCR’s

+1 !
