My two cents are use TE for TE and QOS for QOS it's just sooo much simpler that way.

Even with under/overflow you're always gonna be trailing, there's this bin packing problem, it's not deterministic especially during failures and for anything accurate the amount of state goes through the roof so the solution doesn't scale as a result (though the last bit can be solved through SR and SDN controller). 
I'd be interested in what problem you're facing that can't be met with diffserv hence intserv needs to be employed -note the TE bit (even with class based tunnel selection) is orthogonal to this question.
