I view tilt lockout (and other lockout mechanisms such as altitude@time) as secondary safeties. The #1 requirement for airstarts is that your rocket must be stable to begin with, in any possible configuration that you're gonna fly. Have you ever seen an Estes two-stager, with no lockouts at all, skywrite? (Not counting fins shredding off...) Nope... that's because they are designed to be stable. Secondary mechanisms prevent bad things from happening when something doesn't go right... they're not a way to make it "easier" to do airstarts by letting your electronics take care of the messes. If you build your rocket well, do a good simulation prior to your flight, and set up your electronics accordingly (which you should be doing anyway), there isn't much difference between using tilt lockout or altitude lockout.
This assumes that you're the average rocketry hobbyist and not going crazy high... at 100K+, everything is different, including instability remediation. If you start tumbling at 100K, your electronics aren't going to save your butt there, either.
