Yes, Meraki is not the platform for very special requirements. This is what the Catalyst etc. platforms are for.
But also with the restrictions on Meraki, I really prefer running the general network on Meraki with all its benefits and add specialised devices where needed. Like the 3560CX for MacSec, an ASA/FTD for extranet Site-to-Site VPNs or a Catalyst1000 or CBS as a WAN switch.
