    No, I don't want to have to manage both MPLS and tunnels. That only adds complexity.

WH> with SRv6+ you have to do the same, btw this is no longer MPLS in the strict sense as with LDP/RSVP, it is a tag to make a fwd decision on. Look at it as 32-bit SID which is signaled in IGP. So you are just running an IGP and if you have services, probably MP-BGP or native BGP. 
I am not sure but some people have perception this is MPLS as per RSVP/LDP but it isn’t. it is a tag that represents a prefix-SID/adjacency SID. Nothing more and nothing less.
    
    Cheers,
    Sander
