Will a single /27 get fully routed these days?

I expect the party that paid good money for the address space, and the 
party who they paid, and their respective attorneys, will strenously 
disagree with you, but as I noted, there's other places to discuss this.

Yeah, yeah, we did that, we have buttloads of V6 space, but we need this 
stuff to work now, not in 2025.

I'm fully dual stack both at home (T-W native) and on my servers (HE 
tunnel to my LAN), and v6 is still painfully flaky.  Just this afternoon, 
my home network started acting like someone had poured glue into it, 
because of an internal T-W routing screwup so that my router was reachable 
over v6, but the /64 they assign to my home network wasn't.  When I turned 
off v6, everything worked just dandy again.  Now the v6 routing seems to 
be OK, until the next time it happens.

Re the /28 with no enclosing space, see the PS to my previous note you 
seem to have missed.
