I am bit wary of L2 extension protocols when it regards scalability of the infrastructure, specifically for large networks (I guess that an alternative to STP needs to be used here?).

Then you say “implemented", are you referring to “coded an implementation of VXLAN” or “installed something that knows VXLAN and put it in production” ?

I’ve done the latter, and it works very well. It solved the same problem your $DAYJOB wants to solve for us.
Instead of trying to stretch a LAG in-between the different locations (the old solution, we now use a VXLAN tunnel in-between “leaf" switches at the the different locations. We use eBGP in-between “leaf" <> “spine” switches/routers.
