Switched from safety wire to zip ties on engine cowling baffles and never looked back

I had a 2005 Cessna 172 come through the shop last month with a loose baffle seal that was flapping around near the number 4 cylinder. The original safety wire was a nightmare to remove because it was rusted into the holes, and I spent 20 minutes just cutting and pulling it out. So I tried using high-temp zip ties rated for 200 degrees instead of the usual stainless safety wire approach. Honestly, the zip ties held just as tight after a run-up test and they took me 5 minutes per side instead of 25. I checked with my IA buddy in Bakersfield and he said as long as it's not a critical control cable area, the FAA's okay with it for baffles on a non-pressurized engine. Has anyone else gotten pushback from a lead mechanic about this swap? I'm curious if there's a specific AD or service bulletin I'm missing.

Is there any spot in aviation where we're not slowly swapping out old-school methods for something way simpler? Feels like the whole industry is shifting toward "does it work and is it safe" instead of "this is how we've always done it.

Honestly, are you seeing that shift more in maintenance or cockpit procedures?
